Winged or wingless, they may be green yellow, pink, white, bronze, dark-brown or black. Sometimes, the wingless form is green and the winged form of the same species is black. The antennae are usually quite long.
Aphids have a pair of tubes at the tip of their abdomens that resemble tiny exhaust pipes.
Also, aphids tend to move very slowly compared to insects that are similar in appearance. Several species may attack strawberries in southern Manitoba. Symptoms of damage Aphids suck plant sap, removing nutrients, reducing yields, and, in some cases, causing disease. Honeydew deposits or sooty mould on the fruit and the white skins shed by aphid nymphs when they moult are clues to the presence of these insects. When aphid numbers are high, strawberries may appear wilted.
