further examination of the written details, and this species should not be considered verified for 

 the Little Rocky Mountains. 



Myotis ciliolabrum (Western Small-footed Myotis) — This species has been documented in the 

 Little Rocky Mountains five times, represented by 6 individuals (Table 2). One female was 

 captured at Azure Cave on 3 June 1996, 1 female was captured at Pond #1 below Azure Cave on 

 9 July 1996, 1 female was captured at Azure Cave on 22 October 1996, 2 females were captured 

 at the mouth of Azure Cave on 16 September 1998, and 1 male was captured at the mouth of 

 Azure Cave on 17 September 1998. These records fill a large hiatus in the known distribution 

 for Montana (Hoffman et al. 1969, Swenson 1970, Swenson and Bent 1977). 



Myotis evotis (Western Long-eared Myotis) — This species was first recorded in the Little 

 Rocky Mountains by Butts (1993), who captured a male on 29 September 1992 at the mouth of 

 Azure Cave. Other records include 1 male captured at Pond # 1 below Azure Cave on 9 July 

 1996 (Hendricks and Center 1997), and 1 male and 3 females captured at the mouth of Azure 

 Cave on 16 September 1998. Recorded calls of this species were reported at Azure Cave on 7 

 July 1996 (Hendricks and Genter 1997). These records fill a hiatus in previous reports from 

 Montana (Hoffmann et al. 1969, Swenson and Shanks 1979). 



Myotis lucifugus (Little Brown Myotis) — This species is the most abundant bat documented 

 from the Little Rocky Mountains. Chester et al. (1979) collected 1 male and 1 female (Montana 

 Fish, Wildlife & Parks collection, NG-607, NG-609) from inside Azure Cave on 2 April 1978. 

 Butts (1993) captured 2 males each on 28 and 29 September 1992 at Azure Cave, and collected 1 

 male and 2 females from inside Azure Cave on 5 March 1993. Hendricks and Genter (1997) 

 reported 12 males and 3 females captured at Azure Cave on 3 June 1996, and 1 male netted at 

 Pond #1 below Azure Cave on 9 July 1996. Other records include 1 female at Azure Cave on 8 

 October 1997, 24 males and 5 females at Azure Cave on 16 September 1998, 51 males and 2 

 females at Azure Cave on 17 September 1998. One skull (MTHP 4063) was collected in Azure 

 Cave on 20 April 1997. This species has been reported during winter in Montana only twice 

 before (Swenson and Shanks 1 979), although it is widespread in the state. 



Myotis volans (Long-legged Myotis) — Chester et al (1979) collected 1 male and 1 female 

 (Montana Fish, Wildlife & Parks collection: NG-608, NG-610) from inside Azure Cave on 2 

 April 1978. Butts (1993) collected a female from inside Azure Cave on 5 March 1993. 

 Hendricks and Genter (1997) reported 1 male captured at Azure Cave on 22 October 1996. 

 Other records include 3 males and 1 female captured at Azure Cave on 16 September 1998, and 6 

 males captured at Azure Cave on 17 September 1998. Two skulls have been collected in Azure 

 Cave (MTHP 4062, MTHP 4075), on 20 April 1997 and 18 April 1998. There are few records of 

 this species in eastern Montana (Hoffmann et al. 1969, Jones et al. 1973, Swenson and Bent 

 1977, Swenson and Shanks 1979), and even fewer winter records. 



Eptesicus fuscus (Big Brown Bat) — This species is the second most abundant bat documented 

 from the Little Rocky Mountains and the first species recorded. A specimen (sex?) was collected 

 in Zortman on 30 July 1910 by H. E. Anthony, and is now housed in the U.S. National Museum 

 (USNM 169668). Butts (1993) captured 2 males at Azure Cave on 28 September 1992, and 3 

 males at Azure Cave the following night. Hendricks and Genter (1997) reported 1 male captured
