When I wonder around on our property and look at the leaves of trees and bushes I often see these long-legged flies. I think this is Condylostylus patibulatus. It belongs to a bigger group, the family Dolichopodidae. Bugguide says there are about 1300 species in our area. The adults and larva are mostly predatory, although some of the larva are leaf miners. I suspect, however, that as with most flies, the true life cycle is known for only a fraction of that number. There are probably a number of undescribed species within that group as well, some of which may reside in my back yard.
