Fruit fly

Typically found near ripened or fermenting fruits and vegetables, as well as drains, garbage disposals, and empty bottles.

Secondary consumers of sugary and fermenting substances; they primarily eat the yeast growing on overripe fruit.

Active year-round indoors; they have a very rapid life cycle, developing from egg to adult in about 8-10 days in warm conditions.

They are considered a nuisance pest and can potentially contaminate food with bacteria and pathogens collected from unsanitary surfaces. However, they are invaluable to science as a genetic model organism.
