During the fly season, myiasis, or the presence of dipterid larvae in tissues, is a common and troublesome affliction of mammals. One of the most commonly encountered forms of myiasis is cutaneous myiasis, where the larvae occur in the skin. Many genera of flies are associated with cutaneous myasis., including the awesome primary screwworm (Callitroga hominivorax), various blow flies, flesh flies (Sarcophaga spp.), and skin bots (Cuterebra spp., Wohlfahrtia spp.).
