July Featured Fact Sheet: Pea Aphids
![](/featured_images/pea_aphids.jpg)
The pea aphid is a pea-green, soft-bodied insect about one-sixth inch long. The adult may be winged or wingless, while the smaller nymphs, which resemble the adults, are wingless. The nymphs shed their shins several times in the normal growth process; these cast-off skins are white and quite noticeable on plants and on the ground. Aphids produce a sugary, sticky material called "honey dew," which is visible on plants in moderate to severe infestations. Alfalfa, clover, and garden peas are the plants on which the aphids usually feed.
