Butterflies

Warmer weather has led to the appearance of early flying butterflies  along the ride on sunny days.
 The speckled wood is seen basking in sunlight, sucking nectar from woodland flowers or patrolling close to the ground. It lays its eggs on a variety of grasses favouring cocksfoot and yorkshire fog.

Quite a few brimstone, the orginal 'butter' fly. The bright yellow male is highly conspicuous as it wanders up and down the ride and through more open areas of the wood. The female is much paler and from a distance easily confused with a Large White. They may lay their eggs on alder buckthorn present in the wood. They rarely settle and when they do are very difficult to spot, resembling a small leaf in colour and shape.

Another frequent visitor is the orange tip,  the female lacks the distinctive orange wing markings of the male. The green mottled underwing shows when at rest. Eggs are laid on cuckooflower and garlic mustard. Not many in the wood, but a few are present around the edges.

There has been a single sighting of the comma butterfly with its ragged wing edges. This lays its eggs on the common nettle and there are several patches around the ride entrance and near the spring.

Another nettle laying species is the peacock, with its lovely bright eyes and a fondness for sunbathing on logs or patches of bare earth. In spring, the willow is a favoured source of nectar.
