Snakefly Season has arrived! Arguably the best season! This Ms. is Genus Agulla If you're asking, "What the WHAT?" You probably live east of the Rockies. Snakeflies are their own thing, Order Rhaphidioptera found west of the Rockies in NA. Beautiful and beneficial! #inverts #becurious 1/2

This is Achrioptera manga, a giant phasmid or stick insect native to Madagascar. The specific epithet, "manga" means blue in Malagasy & it's not hard to see why. Only males are blue. The tiny back wings ("alae") are an example of brachyptery: they're useless for flight, but have other functions.

Most surprising find @ bee aggregation '26 were lots of thick-headed #flies emerging! They're parasitoids of adult bees, grabbing them mid-air to inject eggs into the abdomen. Eww but cool! (I guess not if you're a bee 😂) Here's one on a flower: flic.kr/p/2ocMhfV #Conopidae: #Zodion NC, USA
Two flies a small distance away from each other grasp grass blades above the ground after emerging from bee nests. A fly grasping a blade of grass is still soft and with shriveled wings. It has just emerged from a bee nest below.A view of a heavy-bodied brown fly with large red eyes sitting on the tip of a leaf blade.A grayish brown fly with a yellow face and reddish eyes rests on a white background.
