As the Arctic warms, mosquitoes—and the diseases they carry—float north. A recent study finds Jamestown Canyon virus and snowshoe hare virus present in mosquitoes in Arctic and sub-Arctic regions of North America.

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!

Day 21 of #InsectAdvent

Christmas is a time of over-eating. But we're not the biggest feasters. Hermetia illucens (Black-Soldier fly) larvae are capable of eating up to 2x its own body mass in food per day - the best bio recyclers consuming our waste

Day 20 of #InsectAdvent

Nearly there, eyes on the prize of Christmas Day. Talking of eyes, some of the best eyed creatures are stalk-eyed flies including Plagoiocephalus latifrons (image @bertonemyia.bsky.social) we saw in Costa Rica

Day 19 of #InsectAdvent

Santa has a sac full of presents, so does Villa cingulata but hers is full of sand. Her sac is at the end of her abdomen & here she is twerking to get the sand to coat her eggs (on exit) to prevent desiccation - cool mum 😎

Cover photo - Male Diostracus prasinus Loew (Dolichopodidae) from Kephart Prong Trail in the Great Smoky Mountains National Park, North Carolina, USA. This species has fascinatingly pubescent palpi which shimmer in the light and are used for courting interactions. Photograph by Zachary Dankowicz. Cover of the issues shows a long-legged fly standing on a natural surface staring at the camera. It has green eyes with diffuse reddish stripes and a metallic green thorax. It has a pair of bright white, flat palps around the mouth.

Day 18 of #InsectAdvent - LET IT SNOW

Chionea (Limoniidae) are a genus of wingless craneflies commonly called Snow flies (not found in UK but 'strongly suspected' that they are here...). Adults can be seen scuttling across the snow in the winter

Day 17 of #InsectAdvent.. Big day is almost upon us. Have you hung your baubles yet?

What about this specimen belonging to the most bauble of flies Celyphidae (beetle flies or beetle-backed flies). Mostly metallic with their enlarged scutellum grown over their abdomen
