Lacewings are general predators, being less specific to aphids than some other predators.
They are often most important when other aphid predators are inactive. In addition to aphids, lacewing larvae feed on mites, thrips, soft scales, lepidopteran eggs and other soft-bodied prey. Green lacewings are predatory as larvae. Even the latter group takes some aphid food and may have higher reproduction when aphids supplement honeydew and pollen. Adults are green with transparent wings having an interconnecting network of fine veins.
