Oak-tree Pug Geometridae

Eupithecia dodoneata Guenee, 1857

Description: Wingspan 19-22 mm. Forewings pale ochreous white with darker flecks giving an overall mottled appearance. There is a dark discal spot in the costa and a series of brown coloured patches along the costal edge. The hindwings are similar with a small black discal spot.

Key Identification Features:

Sets:  male upperside

Flight Period: Mid-April to mid-May. Skinner gives May and early June as the normal flight period in Britain.

Status: A scarce species with few genuine records. There are confirmed records from Loughgall, Armagh in the late 1970s, mid-eighties and early 1990s, Hillsborough, Down 1997 and the Argory, Armagh 1998 and 2000. Like many woodland species it has in some areas suffered a decline with the loss of general woodland habitat. It is easily overlooked and probably has a wider distribution that current records suggest.

Ecology: A species that is mainly associated with wooded habitats and hedgerows where its foodplant is often abundant. The larvae feed from late June until August on Hawthorn Crataegus monogyna and oak Quercus spp. It overwinters as a pupa.

World Distribution: Eurasiatic; widespread across Europe and north Africa.

Bradley & Fletcher number: 1853 Agassiz number: 70.157
