and large, toothed mandibles. Pupation occurs within a silken cocoon.

1. Family CONIOPTERYGIDAE (powdery lacewings)

Small, delicate, whitefly-like lacewings with white, mealy wings; hindwings sometimes vestigial; venation reduced and with few cross-veins, the veins not bifurcating near the wing margin (Fig. 50); antennae filiform and many-segmented; compound eyes large; ocelli absent. Larvae more or less pyriform, being distinctly tapered posteriorly; antennae 2-segmented and hairy; legs long and slender (Fig. 51).

2. Family HEMEROBIIDAE (brown lacewings)

Usually small to medium-sized, greyish or brownish lacewings with moniliform antennae; wing with numerous cross-veins and the veins typically bifurcating near the wing margin (Fig. 52). Eggs without a mucous stalk. Larvae fusiform, without tubercles; body hairs short and simple; mandibles untoothed (Fig. 53).

EXAMPLES: Eumicromus paganus, Hemerobius humulinus.

3. Family CHRYSOPIDAE (green lacewings)

Medium-sized to large, usually green lacewings; antennae filiform and typically longer than forewings; wings with few longitudinal veins and with relatively few veins bifurcating near the wing margin (Fig. 54) (cf. Fig. 52); compound eyes prominent and brilliantly metallic. Eggs laid at the tips of threads of mucus that rapidly harden to form a stalk. Larvae fusiform, with prominent tubercles and setae (Fig. 55); body hairs often hooked, enabling the dried remains of prey to be carried around as camouflage (Fig. 56).

EXAMPLES: Chrysopa perla (pearly green lacewing), Chrysoperla carnea (common green lacewing).
