Yellow-sided Clover-sawfly

Tenthredo notha


Body length 8 - 11mm. Very similar to T. arcuata and T. brevicornis, black with pale greenish/yellow markings and yellow legs. This species flies quite late in the summer and, the pictures having been taken in mid-August, suggest it is probably T. notha.


Woodland edge and hedgerows plus meadows with plenty of flowering plants. Adults feed on pollen and nectar from the flowers plus some small insects. Larvae feed on the leaves of White Clover.

Status and distribution

Common and widespread in Britain. Common in Nottinghamshire and regular at Netherfield Lagoons.

Best time to see

June to September.
