emerges from pale green or cream-colored eggs laid on the
host plant and feeds on leaves and owers. Its pupa is an equally
attractive light blue green with gold cones, yellow antennae, and
orange eyes. The adults and caterpillars cannot survive severe
freezes so in winter are found only in warm or tropical areas.
However, adults migrate north every spring as far as southern
Canada, where they produce several generations.
The Variegated Fritillary is a “connecting link” to the
Heliconiinae subfamily, known as the heliconians, especially the
Gulf Fritillary (Agraulis vanillae), whose caterpillar, which is
