Abstract We examined seasonal patterns in lepidopteran prey of Rafinesque's big-eared bat (Corynorhinus rafinesquii) by collecting culled moth wings from March to September 1998 from the floor of the entrance room to a sandstone cave used as a roosting site by a maternity colony. We identified 22 species and 6 families (Arctiidae, Geometridae, Megalopygidae, Noctuidae, Notodontidae and Sphingidae) in the diet of C. rafinesquii from 135 identifiable wings recovered from the cave floor. Twelve… 

Diet of Rafinesque's Big-Eared Bat (Corynorhinus rafinesquii) in West-Central Louisiana

The diet of Corynorhinus rafinesquii (Rafinesque's Big-eared Bat) in west-central Louisiana is investigated by examining fecal pellets collected from beneath 3 bridges used by these bats as day roosts, and it is concluded that Rafinesque’sBig-eared Bats primarily prey upon lepidopterans in Louisiana.

Habitat associations of Rafinesque’s big-eared bats (Corynorhinus rafinesquii) and their lepidopteran prey in bottomland hardwood forests

The importance of forested wetlands to the ecology of Rafinesque’s big-eared bat is confirmed and the benefit of proximally located deciduous forests that provide habitat for their moth prey is demonstrated.

The Foraging Ecology of the Mountain Long-Eared Bat Plecotus macrobullaris Revealed with DNA Mini-Barcodes

DNA mini-barcodes are a very useful tool to analyse the diet of moth-specialist bats and suggest P. macrobullaris probably forages by aerial hawking using faint echolocation pulses to avoid detection by hearing moths.

Foraging and Roosting Behaviors of Rafinesque's Big-eared Bat (Corynorhinus rafinesquii) at the Northern Edge of the Species Range

Data disseminated in this dissertation provide insights into the summer and winter ecology of Rafinesque’s big-eared bat in Kentucky, and can be used to manage populations threatened by habitat loss and white-nose syndrome.

Feeding Habits of the Endangered Ozark Big-Eared Bat (Corynorhinus townsendii ingens) Relative to Prey Abundance

Feeding habits of the endangered Ozark big-eared bat (Corynorhinus townsendii ingens) in eastern Oklahoma, USA, were studied from July 1987 through July 1988. Diets were determined from microscopic

Prey consumed by Corynorhinus townsendii ingens in the Ozark Mountain region

ABSTRACT Moths are known to be the primary prey of the Ozark big-eared bat (Corynorhinus townsendii ingens); however, data do not exist as to which species, families, and sizes of moths are eaten. We

Intra- and Interspecific Responses to Rafinesque's Big-Eared Bat (Corynorhinus rafinesquii) Social Calls

The results suggest that Rafinesque's big-eared bats are not attracted to conspecifics' calls and that these calls may act as an intraspecific spacing mechanism during foraging.

Surviving cave bats: auditory and behavioural defences in the Australian noctuid moth, Speiredonia spectans

It is suggested that this auditory constraint, in addition to the greater flight manoeuvrability of H. ater, renders S. spectans vulnerable to predation by this bat to the point of excluding the moth from day roosts where the bat occurs.

Habitat Associations of Bottomland Bats, With Focus on Rafinesque's Big-Eared Bat and Southeastern Myotis

It was revealed that Rafinesque's big-eared bats (Corynorhinus rafinesquii) were more likely to be captured at dry corridor sites than corridors over water, where as regression analysis revealed a significant (P  =  0.016) relationship between southeastern myotis and percent oaks.

Population structure of temperate zone insectivorous bats in relation to foraging behaviour and energy demand

It is suggested that the flexible foraging strategy of M. evotis allows reproductive females, with their high energy demand, to inhabit areas that cannot support reproductive female M. lucifugus and can exist in such areas because of lower energy demand and, potentially, the use of torpor under adverse conditions.
