Layne (1974) recorded seven bat species from Florida south of 

 Lake Okeechobee. Although Vero is slightly north of this area, it is 

 located in the southern half of the Florida peninsula. Among these 

 seven species, Myotis austroriparius and Pipistrellus subflavus almost 

 certainly do not breed in south Florida, and Layne considered their 

 occurrence in the region to be accidental. The remaining five species 

 comprise the native chiropteran fauna of south Florida: Lasiurus semi- 

 nolus, L. intermedins, Nycticeius humeralis, Tadarida brasiliensis, and 

 Eumops glaucinus — all of which are known from Vero. All six species 

 of bats from Vero, including Eptesicus fuscus, might be expected to 

 occur in that vicinity at the present time, with the possible exception of 

 Eumops glaucinus. Apparently, the chiropteran fauna of south Florida 

 had become established by the early Holocene and has remained essen- 

 tially unchanged to the present time.
