Currant Pug Geometridae

Eupithecia assimilata Doubleday, 1856

Description: Wingspan 17-22 mm. Forewings similar in shape and markings to the Wormwood Pug E. absinthiata, but the wings are shorter and more rounded. The colour is normally reddish brown and the white dot at the end of the sub-marginal line is more evident. Hindwings similar in colour to the forewings.

Similar Species: Wormwood Pug has a more strongly arched costa.

Key Identification Features:

Sets:  male upperside

Flight Period: End of April to late August. Skinner gives May and June as the normal flight period in Britain.

Status: Widely distributed but not commonly encountered. The majority of recent records are from small gardens and wooded estates where the foodplants are found. It is likely to be overlooked in many areas and therefore its present distribution is probably not a true indication of its current status in N.Ireland.

Ecology: This species is associated mainly with gardens and allotments where its foodplants are most commonly found. The larvae feed wild and cultivated currants Ribes spp. It overwinters as a pupa.

World Distribution: Eurasiatic; widespread across central Europe to eastern Asia.
