Sepsis fulgens est une petite mouche qui mime les fourmis (sûrement une Lasius) grâce à sa couleur noire et à ses pétiole (la taille de guêpe typique des Hyménoptères) et post-pétiole (typique des fourmis).

La larve coprophage apprécie grandement les bouses de vache.

I hear it's #BlackFlyDay, so enjoy an adult Hairy Maggot Blow Fly, Chrysomya rufifacies, from our home in Leavenworth, Kansas, USA, September 30, 2022. I love the brilliant metallic colors of some of the blow flies.

Black Onion Fly (Tritoxa flexa) Black Onion Fly from Skillman, Montgomery, NJ, USA on June 29, 2020 at 06:10 PM by Lena Struwe

In honor of #BlackFlyDay and my Dad, a dipterologist, I present to you the black onion fly (Tritoxa flexa), seen in my garden. Those wings! I love the scientific name too, like a play on 'toxic flexibility' :). #iNaturalist #entomology #backyarddiversity

Here's the coolest fly I've seen, Rainieria Antennaepes (according to inat). It's a stilt legged fly that holds its front 2 legs forward to look like antenna, to mimic wasps. It totally fooled me until I took a closer look. #BlackFlyDay #Photography #Nature #Invertebrates

A Woodpecker Fly in the genus Medetera standing upright on a spruce stump. It seems to have longer legs in front, so it almost looks like it's standing on its hind legs. And it has spiffy white whiskers under its eyes.

For #blackflyday here’s a particularly dark, Ornithomya chloropus. Hippoboscids vary a lot in colour, but in the UK O. chloropus is usually much darker than the other species & has dark markings underneath on the thorax and head (on the mesothoracic basisternum & lateral gena to be precise).
