Is this fly famous?

Well now. The story on this fly is, it's about 4mm long. It is a very nervous or active fly. As may be espied, its tibiae and tarsi are remarkably hairy. It has a very long proboscis. It's head is all eyes. At this nonce a great many, maybe a tousand or two tousand of these flies are infesting the Verbesina virginica. This fly deserves fame.

Bombyliidae maybe?
