One of my illustrations to celebrate the fascinating world of Diptera, inspired by fieldwork, taxonomy, and a touch of humor.

Nuclei (orange) and the cell membrane (α-spectrin; teal) are shown in adipocytes.
#FlyWeek fun for #FluorescenceFriday, nuclei and α-spectrin are shown in this stack of adipocytes from adult Drosophila 🔬 #Microscopy #CellBiology

Several tiny flies that were parts of a large cloud of gnats. They are flying with front legs up like they are calling a touchdown in American football.
Wheee! Males gnats swarm to make themselves more conspicuous so females can find them and mate. So if you find a cloud of gnats in your travels, say hello to those lonely fellas looking for a nice lady gnat.

Continuing #flyweek with what I think is a Zodion sp. Found it completely still on a leaf. Likely a bee parasite.

My #FlyWeek contribution:
The Variety of Testis Shapes in Pomace Fly Species
Aren't they beatiful?🌈🪰🔬
An old-school sci-poster meets modern confocal imaging!
#Drosophila testis diversity fascinated even Curt Stern (yes, the human genetics textbook guy!) back in the 1930s.

I want to dissect all their testes and stain them with phalloidin to see what shape they have and how muscles are organized!!! Is that a weird first thought after seeing this picture? #flyweek

A small black flu with green eyes perched on the end of a woody reed.
A stout black fly with yellow fuzz on the abdomen and face. This is a robber fly that look a bit like a bumblebee mimic. It is standing on a leaf.
A yellow fly with green eyes and black wings with geometric clear patches. It is standing on the edge of a leaf.
A bronze fly with eyes that have wild wavy markings on them. It is crawling around on goldenrod.
I've been slacking for #FlyWeek so here are a few fun flies!
White-faced Micropanther (Cerotainia albipilosa), Black-tailed Laphria (Laphria flavicollis), Giant Ragweed Fruit Fly (Euaresta festiva), Wavy Mucksucker (Orthonevra nitida)

Hey, is #FlyWeek still on?? :D I just spent all day adding flies to #DuoNat, hoping that now I can finally get a feeling for how they are all related. Maybe so can you :)

A green bottle fly (Lucilia sp.) in a top down macro shot. They are on a gray plastic (a garbage can) that really shows of the metallic green of their exoskeleton and their red compound eyes. The fly is facing right of frame.
I had no idea that it’s #flyweek

White fly with velvety body surface, transparent wings, black eyes, and five black marks on thorax on a white flower.
Maybe I just missed #WorldBeeFlyDay but here is the prettiest one I’ve found, Apolysis quinquenotata (I think) from Sevilleta NWR near Albuquerque. #Flyweek #insects #bugsky

A mall, fluffy moth like fly sitting on a leaf. Its thorax is hairy grey with black wings and a few small patches of iridescent pale blue scales.
A small black fly sits on the bark of a tree facing down. Its eyes and face are mesmerizing with a pari of digital looking lines running across each eye.
Flies mating on a leaf. They have a large white face and jowls and small maroon eyes. The male is on top and is gently holding her eyes.
A thick yellow green fly with large maroon eyes rests on the underside of a thin leaf.
For the final night of #FlyWeek, just some cool-ass #flies.

Happy World Bee Fly Day! I'll take any chance to show off these cuties we found hiding out in the Creosote during a rain storm at Beaver Dam Wash in UT! Lordotus and lots of Anastoechus (iirc). #FlyWeek #Fliesarecool #WorldBeeFlyDay

A fly with a blue abdomen, yellow thorax, head, and legs, red eyes, and clear wings with black markings. It has a hammerhead shaped head with red eyes at the ends of eye stalks. The fly is standing on the underside of a leaf.
Hello new followers, in addition to birds I spend the warmer months chasing bugs. Here is a fun one for #FlyWeek, a stalk-eyed fly found in the Ecuadorian cloud forest.

Since it's already the end of #FlyWeek (!) I though I would share this painting I did of Rhamphomyia longicauda dance flies (inspired by Matisse's Dance (I), of course) for Dr. Rosalind Murray's #LaurierBiology departmental seminar back in 2022! #Diptera #SciArt

some of the coolest flies, I think, are tangle-veined flies (Nemestrinidae) - here 4 species of Prosoeca in KwaZulu-Natal Museum collection
Prosoeca peringueyi
Prosoeca umbra
Prosoeca longipennis
Prosoeca olivacea

As it is #FlyWeek (!), here's a painting I did a long, long, time ago for my friend (& at-the-time) post-doc labmate Urban Friberg (as Nils Holgersson, on a fruit fly instead of the traditional goose). #DrosLife #Drosophila

Side view of a heavy bodied fly sits on a white background facing left. It has a furry gray body with patches of white with small black spots. Its eye is large and has a large red marking that looks like an exclamation point.
Top view of a heavy bodied fly sits on a white background facing left. It has a furry gray body with patches of white with small black spots. Its eyes are large and they has a large red marking on each.
A heavy bodied fly sits on a white background facing the camera. It's tilting its head that has a pattern similar to a Dalmatian, white with black spots. It's face shows tiny antennae and tiny mouthparts, giving it a cartoonish look.
A large thick maggot on a white background facing left. It's body is dingy as it's covered by numerous small black thorn-like spines, each curving backwards.
Can't have Cuterebra without the CUTE 😍
But watch out if you're a small mammal! #Maggots really get under your skin 🤮

A large horsefly whose abdomen is distended with blood sits on a mountain mint leaf. The fly has green eyes with subtle red stripes and a golden yellow fuzzy body, noticeably reddish where the abdomen has stretched.
Another fly for #FlyWeek:
A blood-engorged Green-eyed Horse Fly (Tabanus fulvulus), Alamance County, North Carolina.
