History
Lennon (1863) stated that it was very rare, but that it had occurred at Dalskairth (VC73). Gordon (1919) found the larvae common in sallow catkins in a wood at Corsemalzie (VC74); they bred from 1st July 1906.
 
During 1978-79 there were eight records from the Rothamsted station at Gatehouse of Fleet (VC73), with a further four records from the Mabie Forest (VC73) station during 1989-90.
 
From 1992 to 2010 there were twelve records from sites like Blackpark Marsh on the Threave Estate and Wood of Cree RSPB (VC73), Castle Loch at Lochmaben and Kirkton (VC72).
 
Only confirmed for VC72 in Riley & Prior (2003).
 
Life cycle
One generation. Overwinters as an egg on the foodplant. Larvae are present within catkins during March and April, with pupation taking place there or on the ground.
 
Larval foodplants
Larvae feed on Goat Willow, Eared Willow and Grey Willow catkins.
 
Identification
The greyish-brown smallish forewing that is fairly rounded with a black central spot makes it a distinctive pug.
 
Habitat
Fens, marshes, damp woodland, ponds and gardens are just a few of the habitats used.
 
Recorders' notes
Care required to separate from other 'pugs.'
