Fruit flies are small, almost gnat-like flies that are attracted to rotting or fermenting fruit. These flies are about an eighth of an inch long, with small brown bodies, clear wings, and bright red eyes. Fruit flies lay their eggs on fermenting foods and moist organic materials, and the larvae will feed on these upon hatching.
Fruit flies can lay up to 500 eggs at one time. The eggs can take anywhere from one week to almost two months to hatch based on the surrounding temperature and the amount of fruit flies already in the location. The female will even put feces on the egg sacs to help establish the larvae develop! Once hatched, larvae take around 4 days to mature. Upon maturity, female fruit flies only need around 8 hours before becoming receptive to courting advances by males.
