Figwort Sawfly - Tenthredo scrophulariae


    One of the few sawflies that is distinctive and easily recognised in both its adult and larval stages. The adult is a large (10 mm or more) black and yellow striped wasp lookalike, but especially distinctive because it has bright orange antennae. The larvae are a dusty greyish white with black spots, and a generally creased appearance.

    Similar Species

    The black and yellow stripes also feature on sawflies in the Tenthredo arcuata group - but none of these have orange antennae.
