I wonder if Sinanodonta woodiana is the only freshwater clam like this observed in Europe. I'm also curious about what distinguishes it morphologically from other species of the genus Sinanodonta.
@pintail As we've discussed before, the Sinanodonta invading Europe appears not to be S. woodiana sensu stricto, but a cryptic species originating in the Yangtze that currently has no correct name:
Bolotov et al (2016) called this "Temperate Invasive Lineage"
Kondakov et al (2018) called this "cf. gibba"
Lopes-Lima et al (2020) called it "cf. woodiana 1".
Further, genetic studies have shown that all the European Sinanodonta are this same species.
With that background, Yes, Sinanodonta cf. woodiana is the only Unionid like this in Europe. The native European species most similar are all in the genus Anodonta. They have very fine umbonal rugae.
They rarely have rays, or reddish tones in the periostracum.
They rarely have pink tones in their nacre.
They are rarely as inflated as S. woodiana often is.
Their umbos barely rise above the hinge.
Their shapes aren't as round as S. woodiana.
There may be some overlap in shape between the roundest Anodonta and the longest S. woodiana.
I don't really know how to tell the difference morphologically between different species within Sinanodonta. In Europe, one doesn't have to: they're all S. woodiana... At least until someone publishes a peer-reviewed paper that says otherwise and assigns it a name.
I should also note that the above discussion of Europe excludes the Volga River system of Russia, where S. lauta has also been introduced in addition to the "S. woodiana" that has been introduced to the rest of Europe.
@pintail The difficulty in separating species within Cristariini is why I have rarely added any identifications to your observations in Korea.
@amr_mn
Thanks for the detailed explanation.^^
and
I always forgot about freshwater clams because I didn't think about them.
The species I call Sinanodonta lauta in Korea is Sinanodonta woodiana cf. 1 bunch.
And the Sinanodonta woodiana I mentioned is a group that was recorded as "Sinanodonta woodiana cf. 2" in a previous paper.
Then, the species recorded as Sinanodonta woodiana in Europe seems to be the same group as the species I talked about as Sinanodonta lauta in Korea.
@pintail Yes, S. lauta and "S. cf. woodiana 1" were each others' closest relatives in Lopes-Lima et al (2020).
If S. woodiana is split (as it appears will happen), the name will apply to "cf. 2" as it was first described from Canton, China. So all of the Sinanodonta in Europe will get a new name.

In the above paper, freshwater clams in Greece were studied. The Sinanodonta woodiana recorded above had the same gene sequence as "Sinanodonta cf. wooodiana 2".
And the appearance is also similar to the object with the same sequence as "Sinanodonta cf. wooodiana 2" in Korea.
@arm_mn
If you give me an email address where I can receive the picture file, I will send you the phylogenetic tree and fas file I drew last year.
@pintail I'll have to re-read the sources... I may have written "cf. 1" when I meant "cf. 2".

Same plant 7 and a half years ago https://inaturalist.ala.org.au/observations/136396802
In dune area. Specimen collected for the Royal Alberta Museum under a research permit.
@mcaterino I checked the specimen and the femora are reddish brown (not as red as the elytra) becoming blackish on both ends. Thanks in advance!
Surprised to see this stone-curlew here at the southernmost end of its range of distribution. It was in a resting position, indicating the possibility of nesting?
Hi Andrew, One or two have been visiting the far south coast in summer for quite a few years now. I'm not sure if anyone has seen them breeding yet, but a friend found them down at the Towamba River mouth one year and thought from their behaviour that they probably were. First record from the area in FSC birdos newsletter was in 1998, and most often seen around Merimbula, maybe just because that's where most of the birdos hang out. Because it is listed as threatened the location is being obscured. Can I ask what the general area was?
Hi Jackie, without giving too much away, due to the Beach Stone-Curlew being listed as Near Threatened, it was observed at Mogareeka. I returned to the area it was found today and could not find the bird. Whether the very strong NE wind had something to do with it I am not sure. I note that most of the other sightings for this species on iNaturalist in the NSW South Coast area were in 2017 and 2018, the most recent being 2020.
On open sand in dunes. Specimen collected for the Royal Alberta Museum under a research permit.
Instratus and ulkei would be candidates for the species. This one from farther north looks very similar: https://www.inaturalist.org/observations/48083150. Thus far the only observations of this genus from Alberta on iNat.
@mcaterino Would you be willing to take a look? Thanks!
I don't see any striations between the primary pronotal striae. A ventral shot showing the color of the metafemora (black for ulkei, red for instratus) would be useful. But I'm fairly sure it's ulkei
@mcaterino I checked the specimen and the femora are reddish brown (not as red as the elytra) becoming blackish on both ends.
Not a bird. Maybe a frog or amphibian? I heard this sound all the time in Puerto Rico but could never locate the source.
juvenile
Hi Chris I wasn’t sure with this one, if you wouldn’t mind, could you help me with the best way to identify to difference.
Hi Dean, it's a juvenile bird and it's between Fan-tailed and Brush from the general shape. The juv Brush would be very mottled with buff on the upperparts producing a lot of contrast. Also it would be more blotchy on the underparts without that obvious contrast the neck/throat has with the belly. It's well illustrated in The Australian Bird Guide.
This looks like a good match for this species, but I don't have any prior experience so confirmation or correction from others would definitely be helpful here. Thanks!
@augustjackson I noticed your helpful comment on my friend's recent post regarding an identifying feature for this species:
https://www.inaturalist.org/observations/146495805
I think I may be seeing holes in the branch axils on my observation, but I'm just getting started with understanding lichens and hoping perhaps you could take a look?
Associated male -
https://www.inaturalist.org/observations/146577288
@mecopteron_bouillon This specimen clearly has bristles on the pronotum (see last picture), which reductus is supposed to lack.
Correct, I selected the wrong species, this is highly tentative anyways as this would be a significant range extension (and it is difficult to count the bristles given the angle and lighting of the photos provided)
There are 20 stout setae on the ventral margin of the rostrum, although if you look at the figure on page 16 (152) of Penny those setae seem much shorter in the members of the nivoriundus complex than what we see here. I'm fairly certain it is not elegans, given the coloration and size (this is about 4.5 mm) differences. Probably just something that is not covered by the female key in Penny 1977
The Nearctic Boreidae not covered by Penny 1977 are as follows. C. dectes, C. tlagu (definitely not applicable). B. bomari and B. insulans. B. insulans is islandic and it's description does not match up with this specimen. B. bomari is closer in distribution but has a distinctly short rostrum. Either this is B. elegans (which seems unlikely given the data present), it is an incidentally introduced palearctic/oriental species, or this may be a new species (I think). I am not in a position to say any of this with certainty, so I would suggest that if you have the time you compare this specimen with the many palearctic/oriental species described since 1977
@emmabittacus you know more about Boreidae than me, what do you think about all of this?
I would love to see the males and any other specimens you can find. I suggest that to the best of your degree with the next few observations you light the subject a bit better and get a lateral, ventral, and dorsal view of the terminalia (and if possible rostrum and nota)
So circling back to my above comment about how the illustration of the rostral setae didn't look like Elegans/nivoriundus, it seems the above is an example of the "fine" setae, rather than the "short stout" setae. I totally keyed this first to elegans, but with this in mind it keys cleanly to nix- not to mention the support of the adjacent male.

Good shot of that long pilosity characteristic of this spp. and pilosus
This is a picture of Bibio articulatus at the Merkle Wildlife Sanctuary in Upper Marlboro, Maryland.

On trail by river. Body length 5 mm. Fell several times on his back and is missing a fore leg. Specimen collected for the Royal Alberta Museum.
Blapstinus has only three species in Alberta: metallicus is more smooth and slightly metallic, pratensis has the macropunctures on the elytra distinctly larger than those on the pronotum, which leaves substriatus. Matches image in Bousquet et al (2018) very well (https://doi.org/10.3897/zookeys.728.20602): https://zookeys.pensoft.net/article/20602/zoom/fig/126/

Interesting RTHA here. Partially/mostly leucistic female. Much larger than her mate, who I also took a couple of photos of.
Love to get your thoughts on this one @a-tristis Mike. Such an interesting bird.
Very cool bird! I've seen a few like this, was able to catch one of them. I haven't read up on it, but someone told me they often get more white feathers the older they get.
The one I caught was near someone's house, and he said he'd been seeing the same bird for 12 years, so I guess having that much white didn't affect it much.
@birdwhisperer Have you read up a lot on birds like this?
Well I'll be! Somebody posted about an all white hawk in Farmington on a falconry facebook page...I dismissed it as quackery! Nice find yo!
Yeah! I first saw this bird as I was getting on the 89 at Kaysville maybe three to four weeks ago, or perhaps a month. But I didn't have my camera with me. I've been searching for her since. She was there again today, so I returned with my camera and it was still quite a chase all around the area. But fortunately got some photos.
With Red-Eared Slider. Is this maybe a juvenile?
Melanistic, likely an older male.
@keey excelente observación y que envidia de evento jeje, haber si nos toca observar :D
I can't really be sure of R. grabowski, but I can be sure that it is in the R. fruticosus complex.
looks more like R. ulmifolius to me but really need better images
see https://keyserver.lucidcentral.org/key-server/data/070a0908-0e03-4f01-8c0d-060b0f000902/media/Html/identify.htm
@rfoster this is part of a population I've been monitoring over time in this reserve, and has previously been ID'ed as R. grabowskii for me by a botanist (from much better photos); this was just a rough shot for the location
(although of course there's a possibility of two or more species growing here sympatrically)
@thebeachcomber Cheers, Thomas. Yes, there's frequently more than one species present, in my experience. However, if you've been monitoring this population that probably rules out R. ulmifolius, as Australian populations have distinctly pink flowers, that wouldn't pass unnoticed. Nonetheless, I'd be interested to see a series of good images of salient features of a single plant that would allow it to be keyed out. Tag me if you have observations that I've missed.
Interestingly, there are many AVH records of R. ulmifolius in NSW and yet no iNat observations that are definite. There's something odd going on there.
https://avh.ala.org.au/occurrences/search?q=taxa%3A%22Rubus+ulmifolius%22#tab_mapView
thanks Ralph, I'll definitely have to go back and take a much better/closer look and get much better photos
I can't find my original observation where I first got this IDed (I must have somehow deleted it??), but here was another one with slightly better photos that was ID'ed as grabowskii too: https://www.inaturalist.org/observations/60803679
but I haven't independently verified that myself
Yes, saw that one but can't ID it reliably from that and I can't see a definite primocane. Is this pop being controlled continuously? Left to its own devices, R. grabowskii sends up very large arching primocanes (see obs below) and their presence rules out many other spp.
https://www.inaturalist.org/observations/145424830
Of course there's also the possibility that your botanist's concept of grabowskii isn't the same as mine (syn. R. anglocandicans), a problem that is widespread in blackberry taxonomy.
not much (not any??) control of it here to my knowledge; I haven't noticed any of those primocanes, so I'm guessing this will probably end up being something else, with the different concepts an issue as you note. In my list I also have it down as =anglocandicans
appreciate it Ralph, this will force me to get to the bottom of this at this site and get the photos needed to key these properly
interestingly, after 2 years visiting this site, I've never seen a single flower on any of these plants
@rfoster went back today and managed to relocate two patches. Still no sign of fruit or flowers, but got what I hope are some better pics
https://www.inaturalist.org/observations/146581244
https://www.inaturalist.org/observations/146581218
is the previous photo of the same plant? Easier to id if the flower id kept with the photo that shows the leaves. Just open the observation, hit the edit button in the top right, add the 2nd photo to the observation and delete the 2nd observation
@metsa, please see 20x photo of white inside. Does this confirm H. imshaugii? Thanks!
@lgerstein78 , possibly. Is this the actual inside of the tube itself (ceiling and floor) or the medulla (which also can be white)? … sorry, but ID’ing via pictures can be challenging (for a non-expert like me).
@metsa, I cut off a tiny section near a tube tip. The white is the inside of the green top side of the tube. I’m guessing that’s the medullary ceiling that Sharnoff references in A Field Guide to California Lichens.
Here’s (pictures #2) the type of picture I look for when I (as a non-expert) take to H. imshaugii . It’s clear that all of the inside of the tube is snowy white. Happy lichenizing!
