Differences in the extent of foraging ranges have also been noted. Bats from the same colony foraged in different areas at least some of the time. The average foraging area for female bats in Indiana was 843 acres (341 ha), but the foraging area for males averaged 6,837 acres (2,767 ha). A male bat used a foraging area of 1,544 acres (625 ha) in Virginia. In Illinois, however, the foraging ranges were much smaller at an average of 625 acres (253 ha) for adult females, 141 acres (57 ha) for adult males, 91 acres (37 ha) for juvenile females, and only 69 acres (28 ha) for juvenile males. Foraging areas used by Indiana bats in Indiana increased throughout the summer season, but only averaged 11.2 acres (4.54 ha) in midsummer.
