Davey, P., 2009: A species occurring in England and Wales becoming less frequent as one heads north, the larva feeding on hawthorn (Crataegus spp.), blackthorn (Prunus spinosa), birch (Betula spp.), sallow (Salix spp.) and heather (Erica spp.).
In Dorset, the moth occurs at low density in open or wooded districts where blackthorn or hawthorn is frequent. It is rarely observed on sandy soils.
The Pale Eggar appears to have become scarcer in recent years, in parallel with the decimation of blackthorn and hawthorn scrub on downland.
