Introduction: The common name of small fruit fly comes from their small size and fondness for fruits as egg laying and developmental sites. The name of vinegar fly comes from the fact they develop in the briny or vinegarlike liquids at the top of imperfectly sealed canned fruits and vegetables.
Habits: Small fruit flies are attracted primarily to fresh fruits and vegetables and those fermenting because of yeast. Materials lose their attractiveness when they begin to decay because of bacteria and fungi. Materials commonly infested include bananas grapes peaches pineapples tomatoes mustard pickles potatoes etc. and fermenting liquids such as beer cider vinegar and wine some species are attracted to human and animal excrement.
