Insect life on Hazel in November

It has been unusually mild this month. There are still leaves on some of the hazel trees in our wood and at the beginning of this week I photographed some of the insect life taking advantage of the foliage. The larva of the Nut Leaf Blister Moth (Phyllonorycter coryli) forms a silvery patch on the upperside of the leaf. There are often several on the same leaf...
The larva of the micro moth (Phyllonorycter nicellii) forms a long mine between the veins of a hazel leaf.
In the folded leaf edges are pupae of the micro moth (Parornix devoniella).
Many insects like the 7-spot Ladybird and the Orange Ladybird seem to prefer to rest on the undersides of leaves. The latter used to be considered an indicator of ancient woodland until the late 1980's but has since become much more widespread. It feeds on mildews.
A Hazel Leaf-roller Weevil (Apoderus coryli).
The Winter Moth (Operophtera brumata) is common anywhere near trees and shrubs. This is a male because the female is wingless.
