Identifying Character The winged members of this order have four membranous wings;the hind wings are smaller than the front wings and have a row of tiny hooks on their anterior margin by which the hind wing attaches to the front wing. Chewing or chewing-lapping mouthparts The ovipositor is usually well developed;may be modified into a saw,drill,or sting The antennae filiform,contain 10 or more segments

Larvae The larvae of most of the sawflies and related forms are eruciform and differ from those of the Lepidoptera in that they have more than five pairs of prolegs that lack crochets and usually have only a single pair of ocelli. In most of the order,the larvae are maggotlike The pupae are of the exarate type
