Original sentence: As a group, vespertilionids employ a range of flight techniques.Some individuals are of relatively slow flying genera, such as Pipistrellus, that manipulate the configuration of their broader wing shape and may give a fluttery appearance as they forage and glean.They rely mainly on echolocation, but they lack the enlarged nose appendages some microbats have to focus nasal  ultrasound emissions, and use their open mouths to project their signal
