Ok so I’ve seen a lot of pinned insects in my time but I’ve NEVER seen wing rests for mosquitoes

The @unirdgento.bsky.social have been charged to give me data about these specimens in the @uniofreading.bsky.social collection because they are FABULOUS

After being rather busy and after much procrastination, today I started on the outline for a new Sphaeroceridae key; this may take a while (a couple of years maybe)! Copromyzinae first, pic of Alloborborus pallifrons @flygirlnhm.bsky.social @sjthomasbotany.bsky.social @dipteristsforum.bsky.social

A long-awaited review of the 400+ fly genera of Hermann Loew is finally out (yep, that's a younger Hermann Loew sans moustache). h/t to Joachim Ziegler for the archival research on his bio and making contact with Loew's great granddaughter to get the portrait.

The photos by @bertonemyia.bsky.social that I shared in the original post were too low resolution to do them justice. High resolution versions of the images can be found at

My first louse (flat) flies of the year! Stenepteryx (Crataerina) hirundinis puparia (Diptera: Hippoboscidae) with flies emerging about 5 months early. I probably should have kept them somewhere cooler!

Don't let this delicate little muppet fly fool you - larvae are voracious predators of armored scale insects! A member of the "gall" midge family, it has abandoned plant feeding for a meat-based diet (like many others).

Day 24 of #InsectAdvent and the flying reindeer have arrived!

Oh no they haven’t…

It’s a Ricardia sp (Richardiidae) that I collected from Honduran Cloud Forest, one of the many species of antlered flies.

Day 23 of #InsectAdvent

As the angels spread their wings, so do the flies. Rhamphomyia marginata (Empididae) are found across Europe & unusually for animals, it is the females that form the flirty swarms. Maybe not such angelic behaviour 😉

my modest collection of flies with WIDE heads 🙇

a hammer-headed Richardia (Ecuador),
a stalk-eyed Chaetodiopsis (Mozambique),
a pointy-eyed Ophthalmoptera (Colombia),
and an antlered Richardia (Colombia)

why though? male-male competition? sexual selection? chime-in if you know!
