Brief SummaryRead full entry
North American Ecology (US and Canada)Poanes zabulon is a year-round resident in the southeastern United States west to the Mississippi River, and as a separate, patchily-distributed population in the southwestern ?four corners? states, Texas and south to Panama (Scott 1986). Habitats are open woods in the east, valley bottoms and high-plains cottonwood in the west. Host plants are grasses. There are variable numbers of flights each year depending on location: one flight in the western U.S., with the approximate flight time June 15-July 31, two flights with the approximate flight times late May-early July and Aug.15-Sept. 15 in the northeast, and several flights between April.1-Sept. 15 in the southeastern part of their range (Scott 1986). Some sources consider these two populations separate species, P. zabulon and P. taxiles, others consider them subspecies of P. zabulon (Scott 1986).
