Glanville Fritillary

It's a medium-sized orange, black and white "checkerspot" butterfly inhabiting open meadows. The males patrol along roads and habitat edges, on the lookout for the less conspicuous females which remain in dense tussocks for long periods. Mating occurs around mid-day, and as the female often continues to fly from flower to flower, mating pairs are conspicuous.
Throughout most of their range they have one generation per year, overwintering as larvae. In warm regions they have two generations per year. In her lifetime, a female lays several clusters of up to 200 eggs on the underside of the larval food plant. She feeds on nectar (with her proboscis) from surrounding flowering plants.
