Excited to share our recent preprint about opsin gene expression plasticity, vision, female colour polymorphism and male mate search in my favourite insect species: the Common Bluetail Damselfly (Ischnura elegans).

A collaboration between and Lund Vision Group, led by our incoming postdoc Natalie Roberts and with Dr. Marjorie Lienard

Widow skimmer (Libellula luctuosa) phone pic, the trick is to move in very, very slowly.

I think this is a female of Crocothemis erythraea ("Feuerlibelle"), but could also be Orthetrum ("Blaupfeil")?

Seen in Southern Bavaria.

Comanche skimmer (Libellula comanche). The pollinator garden has brought in a few species of dragonflies, lots of food webs out there.

Diese zweigestreifte Quelljungfer musste nach der Eiablage erst mal abhängen und chillen.

Hardly ever see the glorious around here so I was very excited to meet this splendid fellow yesterday. Light was horrible and it was windy but this photo is just about acceptable. I don't think it's possible to really capture their amazing iridescence in a photo

got major sunburn sat by the pond watching the bugs but it was worth it (don't be like me and always wear suncream folks)

marmalade hover fly (Episyrphus balteatus), blue emperor (Anax imperator), black tailed skimmer (Orthetrum cancellatum), and tapered drone fly (Eristalis pertinax)

bonus: lots of blue damselflies (Enallagma cyathigerum)

6/11/2023 at Brazos Bend State Park. I was starting to lead a hike around Creekfield when I saw this perched on the wall near the breezway door at the Nature Center from 20 yards away. We all went over for a closer look. After the hike it was still there & it let me scale it. I think it's a *big* Swamp Darner (Epiaeschna heros).

I had a feeling I was being watched ...

I'm really pleased how this turned out. Taken live, in the field, on the banks of the Hudson River in the Adirondacks.

This is a teneral adult dragonhunter, meaning it was emerging from its last molt and could not fly yet, which is why it was such a cooperative subject.

4224 hours until Damselfly July, but who's counting?

Eastern amberwing (Perithemis tenera) obelisking on a hot day. They twitch their abdomens and wings in a way that is remarkably reminiscent of wasps. Zolfo Springs, FL.

RT @JBiogeography@twitter.com

Interspecific body size clines in dragonflies and damselflies change dynamically over macroevolutionary time scales and are shaped by variation in both regional temperatures and predator diversity (birds)

Wonderful to finally get this paper about global body size clines and Bergmann's Rule in published in @JBiogeography@twitter.com with my two eminent co-authors and collaborators @mgomezllano@twitter.com and @JohnTWaller@twitter.com!
