CENTRAL FLORIDA CRITTER OF THE DAY: Bee Killer Robberfly (Mallophora bomboides)
Bee Mimic; diptera; predatory.
Although robber flies are predators, they are sometimes prey for other animals, including spiders, birds, and larger predatory insects like assassin bugs, praying mantids, and even other robber flies. Moles and underground arthropod predators, such as centipedes and ground beetle larvae sometimes eat them. (source: http://www.uky.edu/Ag/CritterFiles/casefile/insects/flies/robber/robber.htm)
