Sawflies

Sawflies are part of the insect order, Hymenoptera, together with bees, wasps and ants. However they are considered to be the most primitive group and form the sub-order - Symphyta. They differ from the bees, wasps and ants in not having a 'waist' and in their wing venation. Most female sawflies possess 'saw-like' genitalia which they use to cut through plant tissue in order to lay their eggs. All sawflies are harmless and cannot sting. In Britain there are around 107 different genera and about 500 species. The actual numbers constantly change as new species are added and others are lost. It is unclear how many can be found in Leicestershire and Rutland as it is a very under-recorded group.

The sawfly species in this gallery are displayed in family taxonomic order according to the UK checklist (Liston 2014). Species within each family are ordered alphabetically.
