Female sawfly laying eggs

A sawfly is an insect belonging to suborder Symphyta of the order Hymenoptera. The sawflies are a group of largely plant-eating (herbivorous) insects. The group is less specialised than the ants, bees and wasps.

Sawflies differ from most other Hymenoptera by their broad connection between the abdomen and the thorax, and by their caterpillar-like larvae. The common name comes from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay their eggs. Large populations of certain sawfly species may cause economic damage to forests and cultivated plants.

As of 2013, the Symphyta are treated as nine superfamilies (one extinct) and 25 families. Most sawflies belong to the Tenthredinoidea superfamily, with about 7,000 species worldwide. Tenthredinoidea has six families, of which Tenthredinidae is by far the largest with some 5,500 species. view more...
