Psilos butterflies

A small woodland butterfly that once rare is now becoming much more common and widespread. Individuals rarely live longer than 10 days but whilst the weather is warm they are continually brooded. This is a unique butterfly as the caterpiller or chrysallis has the ability to overwinter. Both sexes feed on aphid honeydew. The caterpillers feed on Cock's-foot (Dactylis glomerata) and other grasses.
