Tenthredo livida

This species is present in most of Europe.[2] These sawflies mainly inhabit woodland rides, hedge rows and spruce forest edge.[3]

The adults of Tenthredo livida are to 12–15 millimetres (0.47–0.59 in) long.[3] The thorax and head are black, with a large white mouth area and white tips on antennae. Forewings have a white and brown stigma. This species is rather variable in colour. The abdomen is usually black in females, orange-reddish in males.[4]

Adults can be encountered from May through August feeding on small insects and on nectar and pollen of flowers, especially of Apiaceae species (Anthriscus sylvestris, Heracleum sphondylium).[3]

The larvae are polyphagous and are nocturnal grazers,[4] feeding on leaves of a variety of plants (mainly Rosaceae, Betulaceae and Salicaceae species, but also on bracken species).[3][5]
