Comments on General Food Habits

7* A stomach of this high-flying bat collected in August (Sherman, 1939) contained fragments of Homoptera, Zygotera (Odonata), Anthomyiidae (Diptera), Dytiscidae and Scolytidae (Coleoptera), and Myrmicinae (Hymenoptera). Ivey (1959) found individuals hunting flies and mosquitoes in berms and "back-dune depressions" along Florida beaches and dunes.

Life History

Life History Narrative

7* Lasiurus intermedius typically inhabits wooded areas in the vicinity of permanent water. In the southeastern United States, it occurs in both coniferous and deciduous forests, where it is thought to roost during the day in clumps of Spanish moss (Tillandsia usenoides) hanging from oaks. In other parts of its range, L intermedius has been reported as inhabiting palm groves (Davis, 1960; Martin, 1970) and pine-oak woodlands (Jones, 1964; Carter et al., 1966; Carter and Jones, 1978). Baker and Dickerman (1956) found these bats roosting "among dried corn stalks hanging from the sides of large, open tobacco shed" in Veracruz. Lowery (1974) reported L. intermedius to be a solitary rooster. However, "approximately 45 yellow bats were flushed" from a daytime roost in Veracruz (Baker and Dickerman, 1956). Evidently, there is sexual segregation in winter, with maternity colonies forming in the spring and summer (Barbour and Davis, 1969; Humphrey, 1975). Sherman (1944) studied the male reproductive cycle and found that spermatozoa are produced from September until mid-February. Pregnant females have been collected in May (Bailey, 1905; Rageot, 1955; Lowery, 1974; Silva-Taboada, 1979) and June (Loomis and Jones, 1964; La Val, 1967; Martin, 1970). Lactating females are known from June (Lowery, 1936; La Val, 1967; Carter and Jones, 1978) and July (Baker and Dickerman, 1956). Breeding evidently takes place in autumn and winter (Hall and Jones, 1961; Barbour and Davis, 1969) and parturition occurs in May and June (Davis, 1960; Lowery, 1974). Litter sizes vary from two to four, averaging 3.4 in Florida populations (Barbour and Davis, 1969).
