If had my life to live over again, I might knuckle down and follow the science track to an entomology degree. I'd do my studies on long legged flies, maybe in Central America, to study their vast biodiversity, learn how they catch their tiny prey animals, observe their courtship--males display their long sexy legs to the females. Then I'd say with confidence that this is Condylostylus* sp., a common genus in North America with more than 30 species.
