The female ovipositor is usually well-developed and is modified into a sting in many families. Hymenoptera have chewing mouthparts. Most termites are wingless but fully winged adults have two pairs of long, narrow membranous wings that are alike in shape. When winged adults are at rest the wings are held flat over the body and extend beyond the tip of the abdomen. The antennae are long and beadlike.
Termites have chewing mouthparts.
Four large membranous wings covered with scales give Lepidoptera their colour and pattern. The adults of butterflies and moths have sucking mouth parts and have a well developed proboscis for drinking nectar or fermenting tree sap. The larvae, called caterpillars, have chewing mouthparts with well developed mandibles. The antennae of butterflies are knobbed at the end, and those of moths are variable but rarely knobbed. When they are at rest, the butterflies hold their wings together vertically over the thorax while the moths hold their wings rooflike over the body.
