Scientific name: Synanthedon formicaeformis
Late May to early August. A nationally scarce moth with a dense patch of red scales on the tip of the forewing and a singular broad, red band on the abdomen.
This moth can be distinguished from the Large Red-belted and Red-tipped Clearwings by the absence of any red markings on the forewings.
The adults are occasionally seen resting on tree trunks in the early morning. The caterpillars feed inside the trunk of the tree from August to the following May, overwintering as part-grown larvae.
