Natural History:
The caterpillars feed on the fallen leaves and buds of the host plants and probably detritis. Native larval host plants include the cultivated trees Chapman's oak (Quercus chapmanii), laurel oak (Quercus laurifolia), myrtle oak (Quercus myrtifolia), sand live oak (Quercus geminata) and Virginia live oak (Quercus virginiana), and the shrubs dwarf live oak (Quercus minima), running oak (Quercus pumila), wax myrtle (Myrica cerifera) and winged sumac (Rhus copallinum). Other native hosts include the trees scrub oak (Quercus inopina), turkey oak (Quercus laevis) and water oak (Quercus nigra). Native nectar plants include the cultivated tree willow-bustic (Sideroxylon salicifolium), the shrub wild-sage (Lantana involucrata), and the wildflower narrowleaf yellowtops (Flaveria linearis). Other native nectar plants include the shrub sweet acacia (Acacia farnesiana). Weedy native nectar plants include Spanish-needles (Bidens alba var. radiata). Larvae also feed on the nonnative mango (Mangifera indica) and tapioca (Manihot esculenta), and the invasive nonnative Brazilian-pepper (Schinus terebinthifolius).
