Long-toed Water Beetle - Dryops viennensis

Dryops viennensis (Heer)

Yes, this is Dryops viennensis (Heer). I have seen it previously from Restigouche County in New Brunswick, and Webster & DeMerchant (2012) recorded it from there as well as sites in Carleton and Madawaska counties. It is an adventive Palaearctic species and it is interesting to see how it has spread in both Québec and New Brunswick. I suspect that if one looked in appropriate habitats in northeastern Maine one would certainly find it there.

known from

New Hampshire since 1994, but somehow has been left off of the UNH database that is online. However, the record is on DiscoverLife.

caveat:

i have a creeping suspicion that this may be actually another common European sp., e.g., D. luridus (Er.) -- so you better run the specimen past an expert

Dryops viennensis (Heer)

Accidentally imported from Europe, this species has become established in Quebec and may show up in Maine as well, according to Brown (1972) (1). So New Brunswick doesn't seem out of the question. I don't have my literature with me to comment on morphological characters from the photo.

cool... didn't know that -- makes perfect sense

viennensis is the second most common sp. of the genus where i grew up.
thanks again, Brady.

My first

Time seeing this species, so a very cool way to start the day.

Richard, it goes without saying that if you wind up with a series of these critters, several of us (myself included) would love to con specimens out of you!

Thanks so much, and thanks fo

Thanks so much, and thanks for your help to all of you.. I am good at collecting them and photograph them, but identification is not easy for me... and impossible for this one!
