Echolocation:  Typical Lasiurine pattern of oscillating calls, curvilinear                                                                                                                            fish hook shape fluctuating minimum frequency (~35-40K). Due to the similarity of their echolocations calls, files characteristic of these species were combined and identified as LASEBO.  Some calls can be confused with NYHU

Florida Distribution:      Peninsular FL

Foraging Behavior:  Often emerges early in the evening.  Mostly moths. Also beetles, leaf & plant hoppers, ants and flies
