A swarm of tiny black flies drew my attention to a flower cluster. They were mobbed all over a dead or dying bee. I looked for a crab spider dining on the bee, and only when I returned home and looked at this photo did I notice the ambush bug with its beak plunged into the bee’s throat. The flies were minute, the type you might find on a rotting mushroom or decaying persimmon. I presume the scent of the bee drew them in.
