Two Homoneura species flies mating. The genus Homoneura belongs to the subsection Acalyptratae, a diverse collection of fly species that have two traits in common: they lack calypters, and none of them are obligate blood-feeders. The latter is surprising in that this is a life history that is common throughout the remaining Diptera.Photo: Muhammad Mahdi Karim
