Cranberry Fritillary
Description:
The Cranberry Fritillary inhabits raised bogs and wet heaths, mostly in sheltered places at the edges of woods, or in clearings. Open water is often in the neighbourhood.
The female lays her eggs singly on the leaves of Cranberry (Vaccinium oxycoccos) and Marsh Andromeda (Andromeda polifolia). The caterpillar goes into hibernation in the moss layer just after hatching, only beginning to feed and grow the following year. However, in adverse conditions, the caterpillar may hibernate a second time. It pupates low down in the vegetation.
It is usually single-brooded.
