Harvester (Feniseca tarquinius)
Above and below: A Harvester - perhaps my most wanted eastern U.S. butterfly species - a mind-blowing find here in my home county (Anne Arundel, Maryland, 6/3/2012). Not only is it beautiful and locally rare, it has the distinction of being the only carnivorous North American butterfly. The caterpillars feed on wooly aphids and similar tiny insects, while the adults sip aphid honeydew. They do not nectar on flowers. Too cool.
