Published information about the diet of eastern small-footed bats (Myotis leibii) does not exist. Feces of 39 M. leibii captured from May through Sep. in southern New Hampshire contained eight orders of insects, spiders (Araneae), unidentified arthropods and vegetation. Moths (Lepidoptera), true flies (Diptera) and beetles (Coleoptera) composed most of the diet. Diet of adult males contained significantly fewer beetles than that of juveniles, but diet was similar between other demographic groups and across seasons. Presence of spiders and crickets (Gryllidae) in the diet suggested M. leibii captured some prey via gleaning.
