This is a female robber fly in the subfamily Laphriinae, though it's not as fuzzy as many of them are. ID'd by Eric Fisher


Laphria saffrana - Robber Fly

Laphria saffrana - Robber Fly

This beautiful bee-mimic Robber Fly was one of the insect highlights of my Florida trip. The hunter has become the hunted in this photo. The prey is an adult Assassin Bug in the genus Pselliopus.


Laphria sp.

Laphria sp.

This large male is a species of Laphria, thought which one it is can't really be determined from a photo. ID'd by Eric Fisher


Lestomyia sp - Robber Fly

Lestomyia sp - Robber Fly

Eric Fisher kindly identified this for me as a Lestomyia species of Robber Fly. It's not possible to ID further without the specimen and he said it might be undescribed!


Machimus occidentalis

Another M. occidentalis, ID'd by Eric Fisher


Machimus occidentalis with prey

Machimus occidentalis with prey

This big robber fly was quite cooperative since he was eating. This photo turned out better than some of the other Robbers, getting them in perfect focus isn't easy (this isn't perfect either)


Machimus sp

Machimus sp

This is an undetermined Machimus, ID'd by Eric Fisher


Mallophora orcina - Southern Bee Killer

Mallophora orcina - Southern Bee Killer

This isn't a bee, but actually a Robber Fly. The Asilids of the genus Mallophora strongly resemble bees in the genus Bombus. They actually prey on them as well. This is a mating pair, though the second one is out of focus

Family Asillidae

This is a very tiny robber fly eating an even smaller fly. It was ID'd by Dr. Eric Fisher (as are most of these Cali robbers). It was found in the Sierran foothills of Pollock Pines.


Pogonosoma ridingsi

Pogonosoma ridingsi

This is the best find from my Lake Tahoe trip. Dr. Eric Fisher ID'd this as Pogonosoma ridignsi and said that it's not very common. It's in the subfamily Laphriinae. This is also one of the cuter robbers I shot.


Proctacanthus fulviventris
