This bug landed at our table at our local pool. It was carrying a bee & sat there for a few minutes with it’s stinger in the bees head feeding on it.
This is not an Assassin Bug. It is a Robber Fly in the genus Diogmites, a group known as the Hanging Thieves because they often hang from one leg while feeding. They take prey on the wing, and this unfortunate Honey Bee stood no chance against such a formidable predator. While Hanging Thieves and other Robber Flies are considered beneficial predators, they do not distinguish between eating beneficial pollinators and agricultural nuisance insects. The mouth of the Hanging Thief is adapted to pierce and suck fluids from the body of the prey. Hanging Thieves do not sting.
