Six-belted Clearwing Bembecia ichneumoniformis
([Denis & Schiffermüller], 1775)
Wingspan 15-21 mm.
Locally distributed in the southern half of Britain, this species inhabits calcareous soils including chalk downland, quarries and sea-cliffs.
The foodplants are bird's-foot trefoil (Lotus) or kidney vetch Anthyllis vulneraria), the larvae feeding in the rootstock.
The day-flying adults are on the wing between June and August.
