Observation of the Week, 11/24/16

Our Observation of the Week is this Zenithoptera dragonfly, seen in Peru by @cullen!

Cullen Hanks’ involvement with nature “started when I was a kid, and never stopped,” he says, and he’s now part of the Texas Nature Tracker program, which is “a citizen-science monitoring effort designed to engage the naturalist community and contribute data on species of concern in Texas.”

This stunning dragonfly, however, was found far south of Texas. Cullens says he was visiting Peru and was in a dugout canoe with his father, “in an oxbow off the Madre de Dios river. We were going for Sunbitterns, but not successfully. We heard them but never saw them. While out I saw the Dragonflies, so I switched taxa and focused on them. They were brilliant.”

Zenithoptera is a genus of skimmer dragonflies (Family Libellulidae) known for the bluish-purple upper surfaces of their wings. Like many other skimmers, they perch often keep their bodies in a horizontal position. iNat user @jimjohnson wrote a blog post about his encounter with members of this genus, and he also notes they’re the only New World genus of dragonflies that sometimes perch with their wings folded together and pointed upright, showing off the dark underside of the wings. He even witnessed a female raising only her hindwings!

Cullen says he’s always been “more of a general naturalist,” even though he’s had many mentors in the birding community, and credits iNaturalist for expanding “the diversity of taxa that I can engage with personally, and the contribution or our citizen science program. We used to focus on just a handful of species, not we collect data on over 1,000 species.”

Observation of the Week, 11/17/16

This Sternotomis bohemani beetle, seen in Tanzania by @joachim, is our Observation of the Week!

When most people think of Africa, they’re picturing the charismatic megafauna - lions, giraffes, lions hunting giraffes (can’t wait to see Planet Earth II!), wildebeests and the like. Joachim Louis and his wife Annette, however, prepared for a seven month safari by taking a four week course covering “the plants and smaller animals that are not in the main focus of tourists coming to Africa.”

With an eye for these less heralded yet equally stunning fauna, Joachim has provided iNat with some great observations, like this Long-winged Kite spider dining on an insect. He found the above Sternotomis bohemani beetle while “hiking with a group in a river valley near Matema. One of the group [accidentally] kicked it with his foot and it landed with the dorsum up...it was dead before, but with the abdomen up it was invisible between the leaves. So it was a lot of luck.”

Beetles are an evolutionary wonder. Their basic design (hard shell and a pair of hard front wings called elytra) have been adapted to a multitude of habitats, food sources, and behaviors. About 400,000 beetle species have been described, making up 25% of all known species on earth! Ranging throughout tropical and southern Africa, Sternotomis bohemani belongs to the Cerambycidae family, known commonly as the Long-horned beetles, as many sport quite lengthy antennae. One member of the family is the titan beetle, which is like the longest insect in the world, it’s body length reaching 6.6 in (16.7 cm)!

“My main focus changes from year to year,” says Joachim. “Last year it was primates this year i tried to get all the flowering plants that we saw. Insects, spiders, reptiles, birds and amphibians are always on the list. The problems of conservation, which means the problems of farmers in the remote areas with wildlife keep me busy all the time.”

He and Annette are hoping to get others interested in Africa “and to show them also the small things that are always around when you are on a camping safari.” He came across iNaturalist as he wanted help with identifying many of these smaller species, and “to share my pictures with more people that are also interested in these beauties. It is a good side effect that all observations can help scientists to get better data about distribution of species.”

Observation of the Week, 11/12/16

This Nyridela chalciope moth, seen by @lljohnson in the Dominican Republic, is our Observation of the Week!

Lisa Johnson has led quite a life. “I am a retired chemist, turned sailor, turned teacher, turned amateur naturalist,” she says. “After leaving Florida in 2001 on our sailboat, seeing a bit of the western Caribbean and teaching math and science in a couple of middle schools along the way;  we have settled here in the DR on about 7 acres on the side of a mountain growing food stuffs to eat and share with our neighbors.”

As an amateur naturalist, Lisa’s current interests are documenting the nearby butterflies, moths and birds in the Dominican Republic, and says she really enjoys “sharing my ‘finds’ with the local schoolchildren.”

The incredible Nyridela chalciope moth she photographed was one of dozens of moths that Lisa found one foggy morning while walking her dog. On a wall near one of the village’s three streetlights, she found many moths resting. “I went home, traded my dog for my camera and got back to the ‘moth wall’ before the sun burned off the cloud over and the moths dispersed,” she says. “That morning I took close to 200 photos of moths (one or 2 shots per moth), some in natural light. What a fun morning! What's needed for another moth photo session at the “moth wall”? Street power overnight, foggy conditions at sunrise, and a hot cup of coffee to get me out the door early before the birds and chickens enjoy the moth buffet.”

Nyridela chalciope is a member of the large Arctiinae subfamily of moths, which consists of about 11,000 species. Members of this family are often brightly colored as adults, and many of their caterpillars are covered in setae (“hairs”), giving them the nickname “wooly bears.” What’s really cool is that the adults have a tympal organ at the rear of their thorax, which can make ultrasonic sounds. The moths use these sounds both for mating and defense - they can deter and sometimes even “jam” the echolocation of bats! And some, like the Nyridela chalciope, are mimics of more dangerous animals, such as wasps - note the clear wings on this species. Some will even have yellow and black banding. If you think you see a wasp, look closely and see if it has moth-like antennae and lacks the narrow waist of a true wasp - you could be looking at a wasp mimic!

Lisa submits her findings to iNaturalist, as well as the Butterfly and Moth Association of North America, and has used iNat to also “meet” a few other nature photographers in the Dominican Republic. She says, “I'm encouraged that some of the abundance of nature here, will be better documented. I'm not a biologist and I depend on others with more knowledge to verify my proposed identifications on many of my photos, especially the moths. I'm hopeful that through iNat I will continue to meet the experts!”

Observation of the Week, 11/7/2016

Our Observation of the Week is this rare Patch-nosed Salamander, seen in the southeastern United States by @saundersdrukker!

A herpetology student at Sewanne: The University of the South in Tennessee, Saunders Drukker is in the midst of prepping four papers for publication, which is why there’s a bit of a delay for this Observation of the Week. We’ll give him a pass this time. :-P 

Saunders is currently conducting research on salamanders of the Cumberland Plateau, focusing on the Cumberland Dusky Salamander. “For the past two years I have been going out into the field to find these salamanders, and then map their distribution and habitat using GIS,” he says. “I’ve also done body condition studies, movement, population dynamics and even genetic work on these salamanders.” At the time of this writing, all ten iNat observations of this species are by Saunders.

The southeastern part of North America is a hotbed of salamander diversity, and the Plethodontidae, or lungless salamanders, are believed to have originated in this area. Yet even in a region that has drawn a good amount of salamander research over the years, new species like the Patch-nosed salamander are being discovered. Described in 2009, this species is the only member of the genus Urspelerpes (say that ten times fast), the first new North American amphibian genus since 1961! Not much is known about this tiny (26mm long) salamander, and according to the IUCN it’s only been found in ten streams in Georgia and South Carolina. Unlike most small salamanders, it has five toes on its rear feet (not four), and is the only eastern plethodontid to exhibit sexually dimorphic coloration. 

Saunders came upon the above specimen while on a vacation with his Herp Lab. He recalls, “it was a fantastic moment to see this minuscule animal moving across some moist leaf litter. The animal was photographed quickly and released shortly after.” It’s now the only research grade of its species on iNat.

And of iNaturalist, Saunders says “I’ve always used [iNaturalist] to give people a better understanding of the places I love. From here in Sewanee, to the Hill Country in Central Texas where I grew up I love sharing everything I can about these places. The idea of giving people an in-depth view of the ecology of these places has always been very attractive to me, couple this with getting to see what other people have found there makes iNaturalist a fantastic tool.”

- Like many salamanders, Patch-nosed salamanders capture their food with a projectile tongue, and that tongue is fast. Here it is in slow motion.

Observation of the Week, 10/27/16

Our Observation of the Week is a pair dueling Great White Sharks seen by @serpophaga off of the Farallon Islands!

Located about thirty miles west of San Francisco, the Farallon Islands are small spurs of rock jutting up from the Pacific Ocean and famous for their bird, seal, whale, and shark denizens. Throughout the years, the islands’ wildlife was decimated by seal hunters, egg collectors (500,000 eggs per month were collected in the mid-nineteenth century), and others, but the site is now a protected wildlife refuge. Researchers from Point Blue Conservation Science and the U.S. Department of Fish and Wildlife have studied the plants and animals there for decades, and recently iNat user Adam Searcy (@serpophaga) spent some time on the islands to help with surveys.

“Much of the fall work on the Farallones involves censusing and banding migrant birds,” says Adam. “We attempt to find and identify every bird that arrives on the island every day (and every butterfly, dragonfly, etc.) In addition to this work, there are pinniped censuses and tag re-sighting, cetacean surveys, and shark monitoring. Weather permitting, a sentry is on 'shark watch' for most daylight hours every day for most of the fall season (= shark season).”

This shark attack was spotted by the biologist who was on shark watch and radioed to the others that a “close and large attack” was occurring off the East Landing. Adam says “many attacks we observe are too distant to allow for good photographic opportunities--that was not the case with this attack.” He and others rushed to the site and by the time they got there the shark was “well into feeding on the carcass.” The large amount of blood and the oil slick indicated that the prey was a Northern Elephant Seal, males of which can reach sizes of 14 ft (4 m) in length and 5,000 lbs (2,300 kg) in weight (the females are quite a bit smaller). Adam goes on to say, “as we watched, a second shark appeared and began powering into the carcass alongside the first animal. This quickly turned into what appeared to be a scuffle between the two sharks, with tails flailing above the water. After about ten minutes, the carcass was finished, the blood pool dissipated and the sharks went on their way.”

The Great White Shark population of the Farallones is considered to be genetically distinct from other members of their species, and sharks tagged there have been tracked to Hawaii and Guadalupe Island, which is off of Baja California. Males tend to return every year, females every other year, and many have been identified by researchers who use scars and other markings to distinguish them.

Adam has now returned to the mainland, but contributed nearly ninety observations to iNat during his stint on the Farallones. He says he uses it as “a digital companion to my regular field notes. The community of amateur enthusiasts and experts are also most useful when I branch out into groups that I'm unfamiliar with, e.g., lichens. I posted a bunch of lichen observations from the Farallones and I've been happy to receive assistance in identification from the iNat community.”

Adam is also encouraged by iNat’s large community: “One aspect of iNaturalist that has encouraged me to upload more and more observations (and I've only just begun in the last 8 months or so) is its ability to generate detailed biodiversity data on a scale that was previously unimaginable,” he says. “Having a global army of enthusiastic contributors will lead to more refined understandings of where organisms currently are, where they are expanding, and where they are contracting. Even uploading observations of common organisms across their range may lead to documentation of changes in status and distribution. Citizen science at work!”

- Adam’s kept a blog of some of his adventures, definitely worth a read!

- In 1997, whalewatchers witnessed an Orca and a Great White Shark battle off of the Farallones. National Geographic made a video about it.

- San Francisco PBS station KQED made two short videos about the Farallones, one more about the ecosystem, the other focusing on the life of researchers there.

Observation of the Week, 10/23/16

Marine invertebrates seen by @dougperrine off of Hawaii are our Observations of the Week!

Noted underwater photographer Doug Perrine recently posted quite a few pictures taken during a “blackwater dive” off the Kona coast of Hawaii this month, and they are absolutely stunning, so I thought I’d feature all of them this week.

“These dives date back to a National Geographic magazine assignment given to staff photographer Bill Curtsinger to document the vertical migration of plankton off of Kona, Hawaii, where volcanic mountains plunge deeply into the sea, resulting in water depths of thousands of meters just a few kilometers offshore,” Doug tells me. “Curtsinger hired a local diver / budding underwater photographer named Christopher Newbert as his assistant, and the two of them spent countless hours offshore, initially using a plexiglass cage photographing the myriad bizarre creatures that migrate to the surface at night.”

Soon, most of the dive companies in Hawaii began to offer these dives, and for experienced divers they’ve become quite popular, since divers almost always see animals they’ve never come across before. “People often compare doing one of these dives to taking a trip to outer space. (Or innerspace. One guide says, "it’s like the ‘60s, but without the hangover"),” says Doug. “I love seeing and photographing bizarre animals that I’ve never seen before (or, in some cases, that nobody has ever seen before).” For instance, the Tremoctopus gracilis pictured above is carrying the broken-off tentacles of a Portuguese Man o’ War, which it uses for defense. And, well, I’ll let The Oatmeal tell you about the amazingness of Mantis shrimps, like the larval one below, which Doug photographed.

“Since very few people are able to see marine wildlife in person, my job is to expose them to the beauty of these animals, help them to understand some of the science surrounding them (i.e. act as a translator for the scientists doing the actual research) and hopefully get them to care about, and want to protect, marine wildlife,” says Doug. “I use iNaturalist as a way to share my photographs with scientists researching those subjects, and to enlist their help in getting my subjects identified. Most of my professional experience is with charismatic megafauna, so I know my marine mammals, sharks, and sea turtles pretty well, but plankton is way outside my realm of expertise...it means so much more to me if I can find out what they are, and what they’re doing.”

Citizen Scientist by Mary Ellen Hannibal

San Francisco science and culture writer Mary Ellen Hannibal has recently come out with a new book titled Citizen Science: Searching for Heroes and Hope in an Age of Extinction and part her research entailed covering California Academy of Sciences’ Citizen Science program. 

Not only does Mary Ellen participate in the Intertidal Biodiversity Survey at Pillar Point project (run by @kestrel and @rebeccafay), she also interviewed iNaturalist Co-directors @kueda and @loarie for her book.

I recently had an opportunity to talk with Mary Ellen about the past, present and future of citizen science and the importance of iNaturalist and other projects in crowdsourcing data and engaging the public. You can watch a video (a big thank you to @dpom, @kestrel, and Richard Morgenstein for their photos and footage) of our chat below, and be sure to check out her book!

Observation of the Week , 10/13/16


This Thyreus cuckoo bee seen in South Korea by @whaichi is our Observation of the Week!

An American who’s been teaching English in South Korea since 2007, Paul Bailey has been using iNat to document the organisms he sees on along a river during his walk to and from work. And after nearly  a year of using iNat he’s recently met up with Kim Hyun-tae (@pintail) a few times to look for frogs, salamanders (including the endemic species Karsenia koreana), snakes, and other animals, and says that on their first trip, Mr. Kim “heard about my interest in insects he gave me one of his old macro lenses which I used to take that photo of the Thyreus. so without his help that photo may not have been possible!”

Armed with this lens, he says “I walked further south than usual along the river one afternoon and noticed a large cluster of fleabanes that I wanted to check out for pollinators. As I drew closer I noticed a moving patch of blue, but it was too far away to see clearly and it eventually disappeared into the nearby vegetation...I noticed the patch of blue coming back and it turned out to be a bright blue bee that landed quite close to me on one of the fleabanes.

[With the new lens] I was...worried that I wouldn't end up with any decent pictures so I snapped more than 80 photos while I had the opportunity. And honestly, I did also enjoy watching it buzz around the flowers so it wasn't really a bad way to pass the time.”

Bees in the genus Thyreus are some of the several thousand species of bees known as “cuckoo bees,” which are brood parasites - named after the famous Cuckoo birds. Like other brood parasites, female cuckoo bees don’t actually care for or provision for their young - they instead make other animals do it. In most solitary bee species, a female leaves a provision of nectar and pollen with their egg (or eggs). Once the egg hatches, the larva will eat the provisioned food then pupate into its adult form. A female cuckoo bee, however, lays its egg in the nest of other bee species, and when the cuckoo bee egg hatches the larva eats the provisioned food and will often kill and eat the host larva as well! Due to this fascinating life cycle, a female cuckoo bee doesn’t have scopa, or anatomical structures for collecting pollen, on her body.

Paul’s current interest in nature traces back to an introductory entomology course he took in college, where he “ended up with a pet tobacco hornworm (Manduca sexta), a pair of Madagascar hissing cockroaches (Gromphadorhina portentosa), and a collection of silkworms (Bombyx mori) that I raised on behalf of the entomology department.” So it’s not a surprise he’s found some fantastic insects while in South Korea.

Using iNaturalist “[has] been a great way for me to learn more about the more detailed differences between members of the same Order or Family,” says Paul. “I no longer lump all butterflies together, for example, and now start thinking of them as 'Blues', 'Skippers', 'Brushfoots', etc.” And in addition to documenting the wildlife around his residence, Paul says “I've found myself looking for something to record every time I take a trip to another part of Korea, sort of as a 'wildlife souvenir' of the journey...I haven't made any travel plans based on someone else's observations yet, but it might happen before too long!”

- Here’s some footage of a Thyreus bee getting some nectar. Check out the colors!

- @pintail started a Korean Nature project on iNat, you can find it here. There are more than 13,000 observations in it.

- Blue is not a common color in nature, one reason being that many animals can’t make blue pigments. Instead, many blue animals get their color by creating materials whose structure reflects blue light. NPR has a nice article about this phenomenon.

Bonus Observation of the Week, 10/10/16

This Crystallopsis hunteri snail, seen in the Solomon Islands by @vespadelus, is our bonus Observation of the Week!

There are so many great observations posted to iNat everyday that it’s an embarrassment of riches and tough for me to pick one for Observation of the Week. I contacted Michael Pennay about his amazing snail find but only recently was able to get a reply, as he was out in field.

“The field,” of course, is the Solomon Islands, where he’s been working two and a half years. Originally from Australia, Michael has also worked in Papua New Guinea and says “[I] love the Pacific Islands, there are so many cool things to see and many people have an exceptional intimate understanding of their environment.”

His current work in the Solomon Islands recently involved a biodiversity survey in the highlands of  Makira island, “a three day hike from the coast uphill and a hard slog carrying survey equipment.” Michael says “In the highlands are beautiful moss forests [see below] that are constantly wet. There are mythical creatures called kakamora that Makira legend has it lives in the forests, and seeing these places you could believe it. Being almost constantly wet the forest had an amazing array of orchids and snails.”


The Crystallopsis hunteri snail that Michael found is one of the many cool gastropods he found there (check out this semi-slug). It’s beautiful, of course, but if you look closely you’ll see that its shell is actually translucent! Many juveniles are green, but only some adults are (here are some other photos for comparison), so there is quite a bit of easily noticeable variation in comparison to some other snail species. This is also  the first observation of this species posted on iNat.

Michael continues his field work, using iNat to keep track of some of his finds. “I mainly use iNaturalist as a personal field notebook to record my observations from particular places so I can look back on them...I really love the community ID side of it and appreciate the assistance of other users in identifying species I’m unfamiliar with. There are some amazingly talented and knowledgeable members of the iNaturalist community. I try to reciprocate this as much as possible by providing IDs for species that I'm familiar with.”

Observation of the Week, 10/6/16

This Marbled Newt, seen in France by @blankplank21, is our Observation of the Week!

After hearing about iNaturalist from the story on NPR, Brian Gray says “I uninstalled Pokemon Go for [iNaturalist] and found myself going further and getting more excited about looking for creatures!” On a recent trip to visit his in-laws in France, Brian had a chance to explore their “beautiful warm home surrounded by lush greenery and some forestry,” and “Every free moment was spent on every bee, hornet or spider!...I found some other wonderful creatures that were really pleasant surprises but nothing so spectacular as this Marbled Newt!”

While exploring on a drizzly night, he found some Giant Toads and went on the prowl for more toad-friendly spots when he found several Marbled Newts. “It was my first time seeing a wild live newt...I took a couple of pictures and a short video then left them alone as they crept away, shunning the light of my phone's torch. I was really excited to take those pictures, I wanted to wake everybody in the house up! My parents-in-law are nature lovers too. That's a major bonding point with my father-in-law so I was quite keen to show him. I was also really keen to post it on iNaturalist.”

Marbled Newts are one of the largest newt species in France, with adults ranging from 5 inches (13 cm) to 6.5 inches (17 cm) in length. They range through much of western France and into parts of Spain and Portugal. Like many newts, they migrate to breeding pools during winter and spring (generally February to May), and during this time males grow impressive crests along their back and tail. During this “aquatic phase,” the warty protuberances on the backs of  both males and females smooth out as well. Even when not breeding, males will have a small ridge along their back.

While Brian’s observation was taken in France, he resides in Oxford, England and was born and raised in Nairobi, Kenya. Growing up in Nairobi, he was always fascinated by nature, saying “We still have troops of monkeys (of different types: Vervet, Colobus, Sykes', etc) that pass through neighbourhoods stirring commotion as they proceed. Or the large Marabou Storks that patrol the city dump sites which are as much a fixture of the city as the people. Nature, animals in particular are the points of association with regards to my home country.”

Looking for wildlife has long been one of his hobbies, but Brian believes that using iNaturalist has made him even more passionate and aware of life around him. “Honestly, I wouldn't have found those newts if it wasn't for the pull I felt towards contributing to iNat,” he says. “I really was excited to add that observation and I'm over the moon that iNat and others are getting excited about it as well...it makes you appreciate the organisms you encounter and approach them with more intrigue, level of fascination skyrockets and you value every living thing in your surroundings.”

- All newts are salamanders, but not all salamanders are newts. Here’s an explainer.

- Here’s some video showing two Marbled Newts courting. You can definitely see the huge sexual dimorphism.
