Allantus togatus
This species has been recorded widely south-east of a line between Bristol and York, with isolated records also in Wales, south-west England and northern Scotland. There appears to have been a reduction in observations in recent years (Musgrove, 2023).
In Allantus togatus the fore wing has a dark patch covering the submarginal cells beneath the stigma extending into the middle of the wing. Also in the fore wing, vein cu-a is interstitial with vein m. The body is black with yellowish-white on the tegulae, first tergite and tergites five (or four and five) and the two apical tergites. Legs are black with white on the trochanters, fore and middle femora apices and tibiae. The apices of the fore and mid tibiae and all tarsi are reddish brown.
Larvae feed on various trees especially oaks and sometimes birches and willows.
