Observations on the feeding behavior of the arboreal L. mexicanus mexicanus at Tower Hill in Orange Walk District, Belize, British Honduras, indicates the manner of prey location and suggests an adaptive advantage of this diurnal predator feeding on noctural prey. Leptophis, which feeds on anurans, forages for prey by day, twilight and occasionally after dark, while other sympatric snake genera, Imantodes and Leptodeira, of nocturnal habits, forage for anurans at night. Leptophis, by occypying a temporal niche different from Imantodes and Leptodeira, is able to occupy their same food niche and thereby alleviate possible competition.
