Vapourer Moth antiqua eggs.

Vapourer Moth Orgyia antiqua

 Eggs are laid by the wingless female in a batch on the cocoon, where they pass the winter and hatch in spring. 

Very interesting both for its moth and its very attractive and colourful caterpillar. Winter eggs are supplied for storage in the cool until spring. The larvae normally hatch in May/June or later, and feed on a wide variety of trees, which include Hawthorn, Willows and Sallows, most fruit trees, Hazel, Rose, Lime and Oak. The larvae are beautifully patterned and coloured, and decorated by prominent shaving brush-like tufts. The cocoon is spun amongst the foodplant.

The male moth is delicate, chestnut brown, with prominent feathered antennae, which are used to detect the wingless female, who emerges from the cocoon and rests on it, calling for a male. She lays her egg batch all over the cocoon where the eggs remain through the winter ready to start off the next generation.
