Urbanus proteus

Long-tailed skipper

Its caterpillars roll bean and legume leaves into silk-tied shelters and feed hidden inside, a habit that gives the species its nickname, bean leaf roller.

The Long-tailed skipper is a dark brown, thick-bodied skipper with a metallic blue-green sheen across the head, thorax and wing bases, and long tails trailing from each hindwing; its wingspan runs about 40 to 59 mm.

Caterpillars feed on beans, peas and other legumes, rolling leaves into shelters sealed with silk where they stay hidden by day. Adults fly with fast, erratic wingbeats and visit flowers such as thistle and lantana for nectar.
