• Size: Flies come in many sizes, from one-millimeter-long biting midges to horse flies over an inch in length.
• Color: Black, brown, yellow, and iridescent green are common colors for nuisance fly species and those often associated with dead animals.
• Description: A typical adult fly has three body parts: head, thorax and abdomen. They have two compound eyes, two antennae, and various mouth parts, as well as two functional, membranous wings, and three pairs of legs. Fly larvae are tiny, cream-whitish, legless, and often worm-like.

Flies can be found almost anywhere. Adults of many species are strong fliers, which helps them locate supplies of food for their larvae. Fly larvae are most common in damp habitats, and flies populations are largest in humid places with lots of moisture.

Adult flies feed and harvest their larvae on organic decaying material. This includes, fruit, vegetables, meat, animal, plant secretions and human feces. Both male and female flies suck nectar from flowers as well.

The fly life cycle has four stages. These stages move from eggs to larvae and pupae to adult. The life cycle of a fly begins with the egg. The female house fly can lay anywhere from 75 to 150 eggs in a batch.
