Libytheana carinenta (Cramer, 1777)
Family: Nymphalidae
Subfamily: Libytheinae

Wing Span: 1 3/8 - 2 inches (3.5 - 5 cm).
Life History: Adults perch on branches and imitate dead leaves by holding palps and antennae downward to look like petioles. Males patrol near host plants to seek females. Eggs are laid in small groups on leaves of the host tree; caterpillars eat young leaves. Adults overwinter in the southern part of their range.
Flight: Two broods; May-June, and August. These butterflies sometimes undertake huge migrations.
Caterpillar Hosts: Several species of hackberry (Celtis).
Adult Food: Nectar from flowers of aster, dogbane, dogwood, goldenrod, sweet pepperbush, and others.
Habitat: Forest clearings and edges, thorn scrub, brushy fields, roadsides.
Range: Argentina north through Mexico and the West Indies to southern United States. Migrates to central California, southern Nevada, Colorado, and most of the eastern United States.
Conservation: Not usually of concern.
NCGR: G5 - Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.
Management Needs: None reported.
