Cornish Red Data (2009)

The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.

Pammene obscurana

Range & Status

Listed by Ball (1986) as pRDB3, but generally widespread in Britain and probably not

warranting RDB status (the late E.F. Hancock, pers. comm.). It is widely distributed but local in woods and on moors and heaths where its foodplant Birch Betula spp. grows. Found in northern and central Europe.

Regional Distribution

One Cornish record only, to mercury vapour light at Chyverton Woods in 1980 (Smith,


Habitat & Ecology

The adult flies in afternoon and evening sunshine; the larvae feed on the catkins of Betula spp.


The restricted Cornish locality has not changed in several years but could be vulnerable to replanting.
