Many types of spiders are found in fields and vary greatly in size and color. Spiders are general feeders and will attack or capture any insect they encounter. Spiders are one of the few beneficials that may be found in a field that has been treated with insecticides. Although spiders are not normally abundant in a field, they contribute to the overall natural suppression of pests. Several species of lacewings are found in fields with the goldeneyed or green lacewing being most common.
Adults are smaller and fragile with large membranous green wings.
They can be distinguished by their large, forward projecting mandibles. Lacewing eggs are often found on plants and are easily recognized since they are attached to a long slender filament which holds them above the plant surface. Only the larvae are predaceous. Several species of small parasitic wasps may be seen in fields. Color also varies, but many are brightly colored.
