Eptesicus fuscus)

larger in size.

leaf stem in south Florida. They also move into buildings, bridges
and bat houses.
Food preferences: Insectivorous. They feed on
beetles, planthoppers, true bugs, flies, mosquitoes, flying termites,
flying ants and a number of other insects.
Reproduction: Females usually give birth to
two pups in may or June.
Florida status: Uncommon in north and central
Florida. Rare in south Florida.
Florida range: Found throughout the state except
the Florida Keys.
