Green lacewing life cycle and stages. Tiny oblong eggs, each with a silken stalk, are attached to plants.
Larvae develop through three instars. Loosely woven, spherical, silken cocoons are attached to plants or in crevices,
such as under loose bark. Adults have golden eyes, slender bodies, and are named for their green, lacy, wing veins.
Average development time from egg to adult is about one month.
