Size: approx 9 to11 mm.  The four species within the Tenthredo arcuata complex are problematic to distinguish and the species boundaries are unclear. The complex within Britain and Ireland consists of the species T. arcuata, brevicornis, notha and schaefferi. Unless specimens have been microscopically examined by someone with suitable expertise, we have decided that they should be recorded as part of this aggregate.
