Scientific name: Bembecia ichneumoniformis
Late June to mid-August. A nationally scarce moth with five or six yellow bands on the abdomen.
The males have six yellow bands but the females have only five, both with orange scales on the tip and along the central bar of the forewings and largely yellow legs.
The adults can sometimes be found using sweep nets. The caterpillars feed inside the roots of the foodplant from July to the following May, overwintering as larvae.
