Any of numerous, widely distributed insect species in five families (superfamily Tenthredinoidea, order Hymenoptera).

Typical sawflies (family Tenthredinidae) are often brightly coloured and are commonly found on flowers; the North American pear slug eats pear, cherry, and plum leaves. The larvae of many species in the other four families also damage trees. Argid sawflies (family Argidae) feed on rose bushes and willow, oak, and birch trees. The North American elm sawfly (family Cimbicidae) feeds on elm and willow. The North American conifer sawflies (family Diprionidae) are common, sometimes serious pests of coniferous trees. The pergid sawflies (family Pergidae) consist of a single genus in South America and Australia.

insect
 any of a large group of widely distributed insects that are thought to be the most primitive group within the order Hymenoptera. Adults are wasplike in appearance, although they do not have a constricted “waist” between the thorax and abdomen. Larvae are caterpillar-like and can be distinguished from lepidopterous caterpillars in that all body segments following the three having true legs have a pair of fleshy prolegs (lepidopterous caterpillars have several segments without prolegs). The superfamily consists of five families: Argidae, argid sawflies; Pergidae, pergid sawflies; Cimbicidae, cimbicid sawflies; Diprionidae, conifer sawflies; and Tenthredinidae, typical sawflies.

      Argid sawflies (Argidae) are stout-bodied insects; they number more than 400 species and are distributed worldwide. The larvae of many species feed on rose bushes, willow, oak, and birch trees.

      The preferred food plants of pergid sawflies (Pergidae), which occur mainly in South America and Australia, are oak, hickory, and eucalyptus. The family consists of a single genus, Acordulecera.

      Cimbicid sawflies (Cimbicidae) are large, robust insects easily recognized by their club-shaped antennae. The most common North American species is the elm sawfly (Cimbex americana), a dark blue insect about 2.5 cm (1 inch) long. The larvae feed on elm and willow. In Europe the larvae of Clavellaria amerinae feed on willow and poplar.

      Conifer sawflies (Diprionidae) are medium-sized insects. The family includes several serious pests of coniferous trees. Diprionids are common throughout most of North America except in the Middle West.

      The typical sawflies (Tenthredinidae) number about 4,000 species and exhibit considerable diversity in structure and habit. They are often brightly coloured and are commonly found on flowers. Many are poor fliers. The leaves of pear, cherry, and plum trees are eaten by the destructive North American species Caliroa cerasi, commonly called the pear slug. The larch sawfly (Pristiphora erichsonii) is sometimes highly destructive to larch trees in the United States and Canada. The elm leaf miner (Fenusa ulmi) is sometimes a serious pest of elm trees.
