What to look for
Vermont also has spotted wing drosophila, Drosophila suzukii, which attacks ripe berries on the plant. With humidity around 71 percent, drains and sponges stay damp, and with winter lows near 10F, any fly seen in January is breeding indoors. The kitchen fruit fly is Drosophila melanogaster: tan, red-eyed, about 1/8 inch long, and attracted to anything sweet that has started to ferment. It lays eggs on ripe and overripe produce, the dregs of beer and cider cans, souring mops and sponges, drain film, and sticky residues like maple syrup. Larvae feed for five to six days and pupate, often away from the food, and University of Kentucky entomologists put the full cycle at about a week under favorable conditions. Around St. Albans, two things set the calendar. The harvest from August through October brings the most ripe produce indoors. And syrup, a Franklin County staple, leaves sticky residue in pantries and sugarhouses that does not follow the harvest at all.
