Turnip sawfly (Athalia rosae) on Monk's Hood (Aconitum napellus)
The adults Turnip Sawfly (measuring is 7 - 8 mm long) are found on a wide range of flower heads seeking pollen and nectar. The larvae (when fully grown are up to 18 mm long) feed on the leaves of the Cruciferae family of plants. On hatching, they tunnel within the leaves and then feed on underside of the leaves. Aconitum napellus can be herbaceous perennials or biennials with lobed leaves and racemes or particles of showy, hooded flowers. It is an upright tuberous perennial to tall, with deeply divided, dark green leaves and tall spires of violet-blue, hooded flowers in mid and late summer. All parts are highly toxic if eaten; also harmful via the skin.
