B. Sawflies (TENTHREDINIDAE)

The Tenthredinidae family of sawflies, of which the Turnip Sawfly is a member, has over seven and a half thousand species. This family belongs to the 'super-family' of Tenthredinoidea sawflies which number perhaps eight and a half thousand.

Sawflies are mostly herbivores (rather than carnivores), often black or brown and between 3mm and 2cms in length.

Female Sawflies have ovipositers (egg-laying appendages) that are saw-like, enabling them to cut slits in bark and twigs through which they lay their eggs. From this, they have gained their English family name.

C. Sawfly - unnamed 1 (Macrophya sp.)

This sawfly, seen in the cemetery in June 2023, may be Macrophya alboannulata or Macrophya albicincta. Determining which requires examination of an individual rather than a photograph. Both species are small - at under 5mmm in length. Larvae feed on grasses, sedges and Elder, and the latter feed on Valerian.
