How well one remembers the "Long time ago," AA'ith which
so trivial a thing as the capture of an insect, even though of
no great rarity, is associated. The Browri Hairstreak I first
and indeed for the only time captured on one of two little hills
with an unpleasing designation in the neighbourhood of Wal-
lingford, Berkshire. Barnwell, Ashton Wold, and the neigh­
bourhood of Polebrook, Northamptonshire; near Great Bedwyn
and Sarum, Wiltshire; Coombe Wood, Birch Wood, Darenth
Wood, and Hornsey Wood, near London; Raydon Wood,
near Ipswich, Suffolk; Dartmoor, in Devonshire; and places in
Dorsetshire and Norfolk are also given as localities for it.
It is by no means a plentiful species, though Avidely dis­
tributed.
About the end of August or the first Aveek in September the
Brown Hairstreak is to be taken flying about oak and beech
trees.
The caterpillar occurs at the end of May.
It feeds on the blackthorn, birch, plum, etc.
In this species the Avings extend in width from one inch and
a third, to rather more than one and a half. They are of a
rich glossy brown colour, Avith a short oblong mark near the
middle of the front, outside Avhich is a more or less visible
