Big Cypress National Preserve stands as the only named location among Florida’s 351 evening bat records, set in South Florida’s cypress-dominated wetlands. That’s a single data point, not proof the bat is scarce across the rest of the state’s forests and woodland edges.

May produces the year’s highest report count, closely followed by June and July. Bat detection is strongly tied to survey effort and roost-monitoring schedules, so a May peak in records doesn’t necessarily mean May is when evening bats are actually most active.
