Pachyprotasis variegata
One of the black and white Pachyprotasis species, although the female also has red on the hind femora and tibia. Males lack midline broadening of any white apical margins of the tergites (cf. simulans and do not have a diagonal black stripe on the mesopleura (cf. rapae).
Larvae probably feed on a wide range of herbaceous plants but have been found on potato crops and on the continent on foxgloves.

Flight period: May to June
Plant associations: Solanum tuberosum, Digitalis sp. and probably a wide range of others (potatoes, foxglove)
