Bolded species are known or suspected to be affected by WNS; underlined species are documented carriers of Pseudogymnoascus destructans without WNS [42].

^a Rarely detected away from roosts due to very quiet calls; auto-identified calls may be confused with other species.

^b Auto-identified calls are frequently confused with M. lucifugus; most of these calls may be M. lucifugus.

^c M. californicus and M. ciliolabrum not yet been documented with WNS, but are both believed to be susceptible given impacts to closely related M. leibii in the eastern U.S.

^d Definitive characteristics for hand confirmation rarely encountered for M. volans; unable to assess accuracy of auto-identified call sequences, but proportion of call volume appears consistent with proportion of capture data in Montana.
