Hibernating larvae of Olethreutes mygindiana

The beauty of Cowberry is that it is an evergreen and therefore easily distinguished from Bilberry at this time of year.
On Wednesday 2nd February 2011, I climbed up to my favourite Cowberry patch on Barden Moor to look for the hibernating larvae of Olethreutes mygindiana.
I soon found a couple of hibernacula consisting of spun-together leaves and each containing a solitary reddish brown 5-6mm long caterpillar.
