Anthrax irroratus
Spotted Bee Fly
Anthrax irroratus is a bee fly (family Bombyliidae) widespread across North America, ranging from Alaska and northern Canada to Central America and the Caribbean. Adults are pollinators that frequent flowers, while larvae are parasitoids of solitary bees and wasps in at least five families. The species is one of numerous bee flies that exploit ground-nesting Hymenoptera as hosts.
