Barred Umber Geometridae

Plagodis pulveraria (Linnaeus, 1758)

Description: Wingspan 34-38mm. Adults have reddish brown forewings with a darker central band which is often narrowed towards the middle. The hindwings are slightly paler marked with a single dark line.

Key Identification Features:

Sets:  male upperside

Flight Period: From the beginning of May to mid-June.

Status: Widely distributed in small numbers throughout most counties. In Fermanagh it has been recorded recently from many well-recorded localities including Crom Estate, Tullyreagh Bridge and Gortmaconnell Rock. Recent records for Down include Rostrevor Oakwood NNR and Bohill NNR. It has also been taken at Rehaghy and Cullinane near Fivemiletown, Tyrone. In the late 1970s it was recorded from both Armagh and Londonderry (at Banagher Glen NNR), but there are no more recent records from either county. It seems to favour old semi-natural and plantation woodlands, and small isolated populations may exist in other localities.

Ecology: An attractive woodland species that is seldom seen in more than ones and twos at light. The larvae can be found from June until August on a wide variety of trees including willow Salix spp., birch Betula spp, Hazel Corylus avellana and Hawthorn Crataegus monogyna. It overwinters as a pupa.

World Distribution: Throughout Europe, Korea and Japan.
