NEUROPTERA – CHRYSOPIDAE NEUROPTERA Etymology : Neuro-nerve; ptera - wings. Common names : Lace wings, Ant lions, Mantispidflies, Owlflies.
Characters They are soft bodied insects. Antenna is filiform, with or without a terminal club. Mouthparts are chewing type in adults. Wings are equal, membranous with many cross veins. They are held in a roof-like manner over the abdomen. They are weak fliers Larva is campodeiform with mandibulosuctorial mouthparts. Pupa is exarate. Pupation takes place in a silken cocoon. Six out of eight Malpighian tubules are modified as silk glands. They spin the cocoons through anal spinnerets. Classification: This order is subdivided into two suborders viz.,Megaloptera and Planipennia.
Sub order: PLANIPENNIA
1. CHRYSOPIDAE (Green lacewings, Goldeneyes, Stinkflies, Aphid lions) Body is pale green in colour. Eyes are golden yellow in colour. Eggs are mounted on stalks to avoid predation and cannibalism. Larvae preys on soft bodied insects, especially on aphids. It often carries a layer of debris on its body which provides camouflage. They emit a stinking fluid when alarmed, from prothoracie stink gland. They are mass multiplied and released in fields for controlling aphids.
2. MANTISPIDAE (Mantispid flies). They resemble preying mantids. Prothorax is elongated. Forelegs are raptorial. Femur is armed with powerful spines. Larva preys on spiderlings in the nests of ground spiders. Development involves hypermetamorphosis.
3. MYRMELEONTIDAE (Ant lions) Adult resembles a damselfly. The antenna is long a clubbed. They are weak fliers. Grubs construct conical pits for capturing prey. Larval mandibles are sickle-like with one or more internal teeth. They have dolichasters (Lateral segmental processes fringed with setae).
4. ASCALAPHIDAE (Owlflies) Adult resembles a dragonfly. Antenna is long, conspicuous and clubbed Hypostigmal cell is present in the wings Larvae do not construct pits to capture the prey Adults are aerial predators like dragonflies.
