A Rare Moth is Found in Chile - Observation of the Week, 2/10/19

Our Observation of the Week is this Andeabatis chilensis moth, seen in Chile by bernardo_segura!

Last week, Frank Izaguirre (@birdizlife) messaged me, writing “Tony, check this one out. It just showed up on my feed! So beautiful, even kinda trippy, and a first for iNat,” and directing me to Bernardo Segura’s photos of the insane moth you see above. So it was chosen as Observation of the Day and got a lot of love on social media, including this great comment on Facebook: "The seventies called. They want their wings back!”

What was really cool is that not only did a user who was mostly interested in birds fall in love with this moth, but John Grehan (@johngrehan), a specialist in swift moths (aka ghost moths), of which this species is a member. John and Bernardo connected, and Bernardo will (fingers crossed) attempt to collect some specimens for John in the hopes of collaborating on an article.

“[This find] illustrates the value of iNaturalist in the way it can alert specialists about new species or new opportunities with known species,” says John. “I have an automatic link for new notifications on Hepialidae and this has contributed to at least two publications. And where new species are suspected it is possible to get in touch with the photographer to see if specimens may be obtained in the future.” He says this last part is critical and would like to encourage observers to try and get a specimen if a specialist ask for one and if local rules allow it. John notes that this species is the only known member of its genus, and that those black tips on the gold scales (see below) are “unique to this species as far as currently known.”

So how did Bernardo come across this moth? Well, unlike many moth finds, he heard it first:

Two years ago I was in the beautiful Alerce Costero national park in the rain forests of southern Chile, taking photos of some frogs at night when I saw a big fluffy thing moving in some branches close to me. It was big as a fist and very loud in its movement so at first I thought it was some small mammal like the Colocolo opossum (Dromiciops gliroides) but when I pointed my headlamp towards it I realized that it was a huge moth moving clumsily in the branches, a moth of a species that I have only seen photos of before and was hoping to see sometime, the incredible and kind of mythological to me Andeabatis chilensis.

“Details of biology are poorly or entirely unknown for most ghost moth species,” says John. However, what we know about them is fascinating. Eggs are generally dropped on the ground and “newly hatched larvae of many (all?) species feed on dead plant detritus or fungi before transitioning to live plants.” And when consuming live plant material, many larvae remain on their own, “living in tunnels made of silk and debris or bore into soil or host plants. Most are probably root feeders.“ Adults, like the one Bernardo photographed, lack functioning mouth parts, meaning they often live for no more than a single night - so he was lucky to have found this one!

Bernardo (above), who has a masters in wildlife conservation, says he has “been passionate about nature since I can remember. Always a curious boy enjoying watching bugs and others animals mainly in the Chilean Andes, now I try to immortalize those marvelous findings through photography and to share them to everyone.” He works with a variety of organisms, “from the most understudied and unknown velvet worms to the charismatic wild cats of the Andes.

I’m just starting to use INaturalist and I believe it’s a great way in which everyone can help to improve the knowledge of  species, I’m now uploading years of finding, starting from interesting and understudied animals like Andeabatis chilensis.

- Not only did Bernardo take some sweet photos of the moth, he also shot really nice video of it as well!

Wonderful story. Beautiful moth. It’s a shame that such a large and charismatic moth lacks any common vernaculars. (Probably a consequence of its rarity.) Personally, I’m in favor of “Chilean Disco Ghost”.

Great work and great photo. Seems a shame such a large intricately marked moth only lives a day.....

Congratulations Bernardo! It is very few that scientists in Chile know about this moth, so beautiful and almost impossible to find! Thank you for sharing your exiting discover!

What a beautiful photo! I just remembered I've seen this species back in 2015, on a field trip as a field assistant to study Torrent Ducks (Merganetta armata) in Nahuel Huapi National Park, Argentina. The specimen I found was very weak, so I presume it was dying (it was in the afternoon). I will upload my photos as soon as I find them, now that I know what is it's name! :) Thanks for sharing this.

Blown away by the picture ... but then I started reading the text, and of course, it wasn't long until the idea of "collecting" raised its ugly head. It would be wonderful to think that one day humans will gain proper respect for nature and all the millions of species that we share this planet with, but sadly that is not yet happening, not even with scientists and naturalists who profess a genuine love and wonder for these same species, but still choose to kill.

There are no words to describe such beauty. How lucky you are, and how lucky we are all of us who, through your eyes, have been able to meet this wonderful moth! Thank you Bernardo! Thank you Andeabatis chilensis!
