Tenthredopsis scutellaris, a common sawfly, is a species of the family Tenthredinidae and subfamily Tenthrediniinae.[1]

Distribution

This species is mainly present in British Isles, France, Germany, Italy, Austria, Switzerland, Poland and Romania.[2]

Habitat

These sawflies mainly inhabit hedgerows, meadows, roadsides and forest edges[3]

Description

Adults of Tenthredopsis scutellaris can reach a length of 8.5–12 millimetres (0.33–0.47 in).[3] Thorax is black, with a yellow stripe along the forehead and yellow scutellum and postscutellum. The legs are brown, but the hind legs are black. The wings are clear with brown veins.[4] Sexual dimorphism is not conspicuous, but in males the rear thigh is rather light, while in the females it is dark. Moreover in the females the abdomen is black with a central broad red band.[5]

Biology

Adults of Tenthredopsis scutellaris can be encountered from May through June[3] feeding on nectar and pollen of flowers of Apiaceae species (Heracleum sphondylium).[3] The larvae are polyphagous on a variety of plants, especially on Apiaceae species (Anthriscus sylvestris) and on herbaceous plants (Poaceae species).[3]
