Fruit Flies
Drosophila spp. (mainly D. melanogaster) · Flies & Gnats
Fruit flies are tiny flies that lay their eggs on the moist surface of overripe or fermenting produce, spilled juice, drains and trash. A single forgotten piece of fruit can produce a large indoor population within about a week. They are mainly a nuisance, though they can carry bacteria onto food.
Look for: A tiny fly with a tan front half, a darker rear and bright red eyes that hovers around ripe fruit, wine or the trash can.
