I’ve never played Assassin’s Creed, but I imagine this is the vibe. (Promachus rufipes robberfly with bumblebee prey.) #bugsky #insects #diptera #accidentalrenaissance

Large fly with wings folded over its long body like a cloak, facing a wall with a black and yellow bumble bee belly up at its mercy, with the late evening sun casting dramatic shadows against the wall and providing a Tuscan color palette. There is a long diagonal crack in the wall that originally confused me - it’s not part of either bug’s anatomy.

Want to learn a bit more about identifying calliphorids? Join Team Diptera on our discord, tomorrow! Link in Bio! #Fliesarecool #TeamDiptera #diptera

An event flyer with a light blue background reads "Team Diptera's 1st iNat ID-a-Thon!" at the top in bold black text. Centered over a yellow starburst is a close-up photo of a metallic green calliphorid fly with red circles and arrows highlighting anatomical features labeled "White calypteres???" and "No pollinosity???". The text at the bottom announces: "Join Bennett Grappone on Tuesday, September 8th at 5 pm PST as we clean up the observations for a highly observed but under-identified species of calliphorid fly! You might get lucky and find an extra rare species hiding in the observations!"

The fly on the right is larger, and has glossy black eyes, and a black thorax with a long black and gray striped abdomen. They both have slender black legs.

Love this from #FlySchool2026 student @toldentops.bsky.social! 🥰 #Lauxaniidae is one of the most diverse acalyptrate #fly families. Larvae are associated w/leaf litter, thus super abundant/diverse in forests. They are HIGHLY variable so every time a student finds one they think it's a new family 😂

Friday #Flyday! Here's a romantic pair of ambush bugs (Phymata sp.) on a dinner date. But check out the fly's abdomen. See it? The dark-light patches are opposite on the left vs. right sides. Cool mutation? Gynandromorph? Just a fancy fly? @flygirlnhm.bsky.social @bertonemyia.bsky.social #BugSky 🐙🌿

A macro photo of a pair of ambush bugs, yellow with brownish patches, feeding on a black and white fly they have caught in a yellow flower. The fly's abdomen shows an unusual pattern; the light and dark patches mirror each other on the left vs. right sides of the midline, that is, an area that's dark on the left is light on the right, and vice-versa.

fly with long thin dark body, thin wings folded over abdomen, large dark red eyes, short antennae (which look to me similar to syrphid antennae), prominent white halteres, normal looking forelegs and midlegs, and hind legs that are about twice as long and twice as thick as the rest of the legs and that are spread out way to its sides.

1. EYES
fly: huge compound eyes covering most of the head
bee: smaller eyes on the sides of the head
validity: POOR

2. ANTENNAS
fly: little triangle between the eyes
bee: jointed antennas, longer
validity: OK

3. WINGS
fly: 2 (or fewer)
bee: 4
