Discussion Completely distinctive, the Zebra Longwing does not at all resemble the Zebra Swallowtail. The Zebra's usual flight is slow, feeble, and wafting, although it is able to dart quickly to shelter. Zebra Longwings roost communally at night, assembling at dusk. Hammocks and thickets throughout Everglades National Park are good places to see gatherings of these butterflies.
