What's That Bug? does not endorse extermination

HUGE fly (not a cicada or bumble bee!)
Hi Bug Man,
I1ve lived all my life in the SF Bay Area but have never seen a fly this large (about 1 inch). I1d love to know what it is – any clues? Thank you!

Hi Suzanne,
What a funny photo. This is a Tachnid Fly. They are important biological control agents since they parasitize caterpillars. There are several genuses in the subfamily Tachinae pictured on BugGuide, and we are not sure if your specimen is in the genus, Adejeania, Hystricia, Paradejeania, Protodejeania or some other.
