Brown Hairstreaks and Mill Hill

Brown Hairstreak, Thecla betulae
On Tuesday I did another Mill Hill transect on a sunny day. The butterfly season is definitely on the wane at the site. The three blues are mostly very tatty and numbers were down. The upside is that I saw the Clouded Yellow nectaring and dashing around the meadow where I saw it on Saturday. Results: 41 Adonis Blue, 3 Chalkhill Blue, 1 Clouded Yellow, 1 Comma, 31 Common Blue, 2 Gatekeeper, 63 Meadow Brown, 1 Peacock, 2 Red Admiral, 1 Small Heath, 1 Small Tortoiseshell.
Afterwards I visited Steyning Downland and met Neil and a couple of other Brown Hairstreak enthusiasts. Neil had seen one an hour before, but cloud cover ensured I had no luck.
On Wednesday I revisited Steyning and this time saw six Brown Hairstreaks. Neil saw the same specimens. An excellent day!
