During spring and fall, Indiana bats migrate between hibernacula and summer roosting sites. In New York and Vermont, bats traveled up to 25 miles (40 km) between hibernacula and summer roosting sites in spring. This is a considerably shorter distance than what is seen in the Midwest, where bats may travel up to 300 miles (500 km). Many males remain close to hibernacula during the spring and summer rather than migrating long distances like females. Occasionally, they even roost within hibernacula during the summer. Males also roost in caves and trees during fall swarming. Few data exist for the roosting requirements of Indiana bats during spring and fall migrations; data indicate that requirements during these times are similar to summer needs in that the bats chose large trees with direct sunlight and exfoliating bark.
