Thomas's yellow bat (Rhogeessa io) is a species of bat from the family Vespertilionidae.
Taxonomy
Thomas's yellow bat was given its binomial nomenclature by Oldfield Thomas in 1903 as Rhogeessa io.[1] Synonyms for the species include Rhogeessa bombyx (Thomas, 1913), Rhogeessa riparia (Goodwin, 1958), and Rhogeessa velilla (Thomas, 1903).[2] The Thomas's yellow bat was formerly included as a subspecies of the black-winged little yellow bat, but was considered distinct in 1996.[2]
The species needs taxonomic review for a number of reasons.[1] One of these reasons includes the possibility that subspecies of the Thomas's yellow bat may be their own species.[1]
Thomas's yellow bat inhabits many habitats, such as both evergreen and deciduous forest, thorn shrub, open areas, and villages, though it appears to favor slightly disturbed deciduous forests.[1] Like other species in its genus, the Thomas's yellow bat can take refuge in buildings and hollow trees, although its roosts are unknown.[1]
The species is crepuscular, with peaks of activity within an hour of both dusk and of dawn, flying low to the ground along wide trails or roads.[1] The Thomas's yellow bat is an insectivore, feeding on small, flying insects and with established hunting routes among individuals.[1]
The maximum energy of echolocation calls in the Thomas's yellow bat is 50 to 60 kHz.[1]
