Maggots are the legless, soft-bodied larvae of flies belonging to the order Diptera (two-winged insects). Common maggot-producing flies include house flies (Musca domestica), blowflies (Calliphora), and flesh flies (Sarcophaga). Coleoptera = beetles; Lepidoptera = butterflies and moths (caterpillar larvae); Isoptera = termites. Maggots are important in forensic entomology for estimating time of death.
