Flies are holometabolous, therefore they have four distinct morphological stages; egg, larva (maggot), pupa and adult. After hatching from the egg, larvae molt twice as they grow. Molting of maggots is difficult to see. Larvae are maggots with a legless soft body except for the dark mouth hooks. Pupae are dark, and look like a small barrel.
Males Fly and females are hard to distinguish. Females are usually larger and can extend the tip of the abdomen to form an ovipositor which is used to lay eggs. Sometimes males have enlarged eyes which meet on top of the head.
Larvae feed on decaying meat and feces. Adult flies feed on sugary food of any kind, including nectar and rotting fruit.Flies live in garbage and wherever animal feces are available. Dead animals attract flies within hours after death. Most flies are diurnal.Many birds, bats, spiders, and insects such as dragonflies eat the adults. Predatory and parasitic insects eat the larvae.
