Did You Know…
Males perch on trees and shrubs to watch for receptive females, rarely patrolling. Males are territorial and will strike out to meet other males, dragonflies and even birds (Pyle, 2002). Females lay eggs singly on the tips of host plant leaves; caterpillars eat leaves. Third-stage caterpillars overwinter in shelters made of leaves. The mottled black, gray and white coloring of the larvae make them resemble a spiny bird dropping and thus offer some protection against predators (Angel, 2005).
