Marbled Whites and a Tawny Owl

Tawny Owl, Strix aluco
On Thursday I was advised by Neil Hulme  that the Marbled Whites at Fairmile Bottom were worth a visit. While there Neil spotted a white form of the Bee Orchid. One Marbled White had been captured by a Crab Spider. These arachnids account for considerable butterfly predation. In one location recently one spider captured several specimens of an endangered butterfly which is in serious risk of extinction at the site. Marbled whites are one of the  hosts for the larvae of a red parasitic mite, Trombidium breei, which do not harm the butterfly. Two interesting articles about this:

Afterwards I visited Houghton Forest, where I found a Fungus Weevil and a Peacock larva. As I was returning to the car park I heard a Turtle Dove at 4:30pm. I entered the woods in search of it and came to a glade. A large brown bird then flew off from a tree and perched in an adjacent one. I was able to get some shots of a beautiful Tawny Owl. When it flew it seemed much larger than it really is (15 inches tall).
