Fruit fly

Typically found near ripened or fermenting fruits and vegetables, kitchen drains, and trash cans.

Feeds on yeast and bacteria associated with decaying organic matter and fermenting sugar.

Has a rapid life cycle of about 8-10 days and is most active during daylight hours, specifically at dawn and dusk.

Primarily a nuisance pest that can contaminate food with bacteria; however, they are highly valuable in scientific research for genetics and developmental biology.
