The Mediterranean gecko, Hemidactylus turcicus, is a small nocturnal lizard introduced into the U.S. A stable population on the campus of Westark Community College in Fort Smith, Sebastian County, Arkansas represents the northernmost U.S. population presently known. We report data on microhabitat usage, feeding behavior, reproduction, and activity patterns. This gecko is active on the outside of buildings during warm months of the year and occasionally inside buildings during the winter. It is most abundant on buildings with many crevices that are used as daytime retreats. It avoids direct illumination of artificial light and usually perches at heights greater than 7.5 meters. Geckos are not territorial during their nocturnal foraging period and employ a sit-and-wait tactic to capture insect prey. Eggs are laid in mid-June and hatch in mid August; this reproductive season is later and shorter than it is in more southern populations. Communal nesting may be employed. A nightly bimodal activity pattern was observed with peaks of activity at 2300 and 0300 after which activity declined rapidly.
