Subsequent papers (Needham and Heywood,1929; Bick, 1959; and Houston, 1970) increased the species list to 18. Bick (1978) was apparently unaware ofHouston's (1970) paper and relistedthree species as new records. This study provides a list for Arkansas damselfly species, their known flightseasons, and their distributions by county.Adults of most species occurring or possibly occurring in Arkansas can be identified using the keys of Johnson (1972). The exceptions, severalLestes species and Enallagma aspersum, are included in Walker's (1953) keys.The data presented are a compilation of the contributions of all sources listed in the Acknowledgements, pertinent published records, andmaterials collected by myself. The museum collections at the University of Arkansas-Fayetteville and -Little Rock were visited.Treatment ofcaptured specimens was as follows. While still alive,specimens were placed inpaper triangles with wings inthe normal restingposition and heads rotated 90° to the left. The triangles were placed in science-grade acetone for a period of 18-24 hours. These may remain inIme forup to five dayswith no detrimental effects. Next, each specimen was removed from the acetone, dried, identified, and transferredclear cellophane envelope with a 3 X 5 inch data card. These curatorial methods are advantageous in that they better preserve many colorsdoes air drying, storage space is minimized, and, since each envelope contains but one specimen, association ofparts after breakage is facilitated.IThirty-three damselfly species are currently recorded for Arkansas. The flight season formost of these extends from spring through summeris, and formany species persists into mid-autumn (Table 1). Temperature appears to be a major factor controlling their emergence. Somes vary from this generalization, however. Enallagma divagans seems tobe a spring to early summer species, as was noted by Johnson (1972).rina titiain Arkansas appears inmidsummer and flies through early autumn. Johnson (1972) stated that it is characteristically a spring formtral Texas. Species of Lestidae are highlyadapted for life in temporary waters, and many have a diapause in the egg (Corbet, 1962). Thises a characteristic massed, synchronized emergence on the species, followed by a relatively short flightperiod. Lestes disjunctus australisiextended flight season in Arkansas, but L. inaequalis and L. rectangularis are spring fliers, while Archilestes grandis adults are presentIthe late summer and autumn (Table 1).Twenty-four Arkansas damselfly species (73%) are of the Eastern United States or Eastern U.S.-Tropics fauna, and seven species (21%)are Transcontinental or Transcontinental-Tropic in distribution. They are therefore likelyto be found in any Arkansas county, provided suitablehabitat is present. Ischnura posita and Anomalagrion hastatum are the most common forms, having been recorded in 69 and 54 counties, respec-tively (Table 2). These two species can be found in association with a variety of aquatic ecosystems, and they apparently have a wide range oftolerance for several environmental parameters.Ischnura ramburii and /. verticalis are two species of the Eastern U.S. which reach a geographic limit in Arkansas. /. ramburii has beenreported from Louisiana, Mississippi, Texas and Oklahoma, but not from Kansas, Missouri or Kentucky (Bick, 1957; Bick and Bick, 1957;Montgomery, 1967; Johnson, 1972; Huggins et al., 1976; Lago and Stanford, 1979). Its Arkansas distribution reflects that situation in that 19of the 21 counties from which itis recorded are in the southern half of the state. Seemingly disjunct populations in Craighead and WashingtonIuties are the exceptions. /. verticalis has been reported fromnorth of a line connecting Lake Texoma (Oklahoma-Texas state line)withextremeleast Tennessee (Bick,1957; Bick and Bick,1957;Montgomery, 1967; Johnson, 1972;Huggins et al., 1976; Lago and Stanford, 1979; JohnsonConey, 1980). Its Arkansas distribution concurs with those data, as the 10 counties listed are northcentral and northwestern.Argiaplana apparently has a limited Central U.S. distribution, as it has onlybeen reported from Texas, Oklahoma, Kansas and Missouri(Bick, 1957; Montgomery, 1967; Johnson, 1972; Huggins et al., 1976). Tenof the 11 Arkansas county records for this species are in the northernQuarter of the state. Four of the six county collections made by me were from springs or spring-fed steams. Ihave not been able to determinethe specific habitat for the remaining five county collections. Huggins et al. (1976) listed four of their seven county collections for this speciesin Kansas as being from springs.1Argia immunda has been reported from only Mexico, Texas and Oklahoma (Bick and Bick, 1957; Johnson, 1972). Bick and Bick (1957)ted this species to be frequent and locally abundant in southern Oklahoma, but absent in the northern part of the state. The Washingtonty, Arkansas, record is the most northern and eastern location forA. immunda.iJohnson and Westfall (1970) have remarked that Ischnura kellicotti is one of the few temperate latitude odonates to have developed anrentlyobligatory relationship with specific plants. The plant inthis case is a water lily,Nuphar (spatter dock). Myfirst collection of this specieson 27 July 1982 from Berg Lake at the western city limit of Camden, Ouachita County, Arkansas. This population was associated withphaea odorata Ait.,the sweet-scented water lily,and is the first record of this particular association. A subsequent collection of /. kellicottimade on6 September 1982 from a pond on the S side ofU.S. Hwy.270, 1 mi E of Poyen and immediately W of Frances Creek, in Grantnty, Arkansas. This pond contained Nuphar.»Aperusal ofthe damselfly species lists for neighboring states (Bick, 1957; Bick and Bick,1957; Macklinand Cook, 1967; Montgomery, 1967;son, 1972; Huggins et al., 1976; Lago and Stanford, 1979) reveals that at least eight additional species may be found in Arkansas. Those» include Calopteryx dimidiata (Burmeister), Lestes congener Hagen, L.dryas Kirby,L.forcipatus Rambur, Amphiagrion saucium (Burmeister),magrion conditum (Hagen), Enallagma dubium Root, and Nehalennia integricollis Calvert.87Journal of the Arkansas Academy of Science, Vol. 37 [1983], Art. 30Published by Arkansas Academy of Science, 1983I88Arkansas Academy of Science Proceedings, Vol. XXXVII,1983Arkansas Academy of ScienceTable 1.

The western subspecies, M.k.keenii, is found from Alaska southget Sound in Washington. The eastern race, M. k. septentrionalis, ranges from Saskatchewan to Newfoundland and south tonorthern Floridaiand Shump, 1979).Ithas been suggested by van Zyllde Jong (1979), based on a study of Canadian specimens, that M. k.keenii and M. k. septentrionalis aredistinct species. Inthat case, the Arkansas form would take the name M.septentrionalis. At this time it is notclear whether or not this separationwill be accepted. Therefore, we utilize the name M. k. septentrionalis for the Arkansas form.Myotis keenii is a medium-sized Myotis with long ears (17-19 mm) and a narrow pointed tragus. The forearm measures 32-39 mm and thewingspan is 228-258 mm; the calcar is not keeled (Barbour and Davis, 1969). Color varies somewhat but the body is usually brownish to reddish-brown above and gray below. The fur is not glossy.Myotis keenii hibernate in caves or mines during the winter where they usually select relatively cool sites, often near cave entrances. Theyoften hang singly and seem to prefer tight crevices and holes. They are never abundant; concentrations of 100 or more ina single cave or mineare unusual (Barbour and Davis, 1969). During summer they roost in a variety of shelters includingunder the bark of trees, behind shutters, andin buildings. They appear to be relatively solitary in their habits, except for small maternity colonies formed during summer.InArkansas, M. keenii is widelydistributed throughout the InteriorHighlands. Sealander (1979) considered it to be "relativelyuncommon"in Arkansas and reported it fromBenton, Washington, Newton, Baxter, Stone, and Independence counties inthe Ozarks and fromPike and Garlandcounties inthe Ouachitas. During a recent study in eastern Missouri, Caire et al. (1979) reported that 141 trips to 77 caves between October 1975and April1976 resulted in locating only39 M. keenii. However, as many as 460 individuals were captured at a single Missouri cave entrance duringone night in June.Since 1968, wehave recorded M.keenii from 15 caves inseven Arkansas Ozark counties, the same six counties reported bySealander (1979),and also from Marion County. Usually 1-3 and not more than 6M. keenii were seen in any one cave. They were found inrelatively large numbersin onlyone cave, Cave Mountain Cave inNewton County. During the winter of1973-74 we estimated 200 tobe present there and during the winterof 1977-78 we found ca. 100 (we did not visit the cave during the intervening years). Since the winter of 1977-78, Cave Mountain Cave has beenchecked yearly and less than 10 M.keenii have been observed there each winter. However, itis important to pointout that because of their preferencefor cracks and holes in the cave ceiling, they could easily be overlooked.INetting at cave entrances during the summer-autumn swarming period indicates that this species is more abundant in the Arkansas Ozarksindicated byobservations ofhibernating bats incaves and mines. Asmany as 40M.keenii have been netted at the entrance ofCave Mountain. However, that number is greater than at most caves netted, where the number captured during any one night is usually less than 10.iCaveMountain Cave, located on Buffalo National River lands, from which the largest numbers of M.keenii have been reported in Arkansas,recently (1982) fenced by the National Park Service to protect the endangered Indiana bats (M. sodatis) and gray bats (M. grisescens) thatnate there from human disturbance. Hopefully, the protection of this cave from disturbance during the hibernation period will result in anase in the numbers of M. sodalis, M. grisescens, and M. keenii that hibernate there.LITERATURE CITEDBARBOUR, R.

The western subspecies, M.k.keenii, is found from Alaska southget Sound in Washington. The eastern race, M. k. septentrionalis, ranges from Saskatchewan to Newfoundland and south tonorthern Floridaiand Shump, 1979).Ithas been suggested by van Zyllde Jong (1979), based on a study of Canadian specimens, that M. k.keenii and M. k. septentrionalis aredistinct species. Inthat case, the Arkansas form would take the name M.septentrionalis. At this time it is notclear whether or not this separationwill be accepted. Therefore, we utilize the name M. k. septentrionalis for the Arkansas form.Myotis keenii is a medium-sized Myotis with long ears (17-19 mm) and a narrow pointed tragus. The forearm measures 32-39 mm and thewingspan is 228-258 mm; the calcar is not keeled (Barbour and Davis, 1969). Color varies somewhat but the body is usually brownish to reddish-brown above and gray below. The fur is not glossy.Myotis keenii hibernate in caves or mines during the winter where they usually select relatively cool sites, often near cave entrances. Theyoften hang singly and seem to prefer tight crevices and holes. They are never abundant; concentrations of 100 or more ina single cave or mineare unusual (Barbour and Davis, 1969). During summer they roost in a variety of shelters includingunder the bark of trees, behind shutters, andin buildings. They appear to be relatively solitary in their habits, except for small maternity colonies formed during summer.InArkansas, M. keenii is widelydistributed throughout the InteriorHighlands. Sealander (1979) considered it to be "relativelyuncommon"in Arkansas and reported it fromBenton, Washington, Newton, Baxter, Stone, and Independence counties inthe Ozarks and fromPike and Garlandcounties inthe Ouachitas. During a recent study in eastern Missouri, Caire et al. (1979) reported that 141 trips to 77 caves between October 1975and April1976 resulted in locating only39 M. keenii. However, as many as 460 individuals were captured at a single Missouri cave entrance duringone night in June.Since 1968, wehave recorded M.keenii from 15 caves inseven Arkansas Ozark counties, the same six counties reported bySealander (1979),and also from Marion County. Usually 1-3 and not more than 6M. keenii were seen in any one cave. They were found inrelatively large numbersin onlyone cave, Cave Mountain Cave inNewton County. During the winter of1973-74 we estimated 200 tobe present there and during the winterof 1977-78 we found ca. 100 (we did not visit the cave during the intervening years). Since the winter of 1977-78, Cave Mountain Cave has beenchecked yearly and less than 10 M.keenii have been observed there each winter. However, itis important to pointout that because of their preferencefor cracks and holes in the cave ceiling, they could easily be overlooked.INetting at cave entrances during the summer-autumn swarming period indicates that this species is more abundant in the Arkansas Ozarksindicated byobservations ofhibernating bats incaves and mines. Asmany as 40M.keenii have been netted at the entrance ofCave Mountain. However, that number is greater than at most caves netted, where the number captured during any one night is usually less than 10.iCave Mountain Cave, located on Buffalo National River lands, from which the largest numbers of M.keenii have been reported in Arkansas,recently (1982) fenced by the National Park Service to protect the endangered Indiana bats (M. sodatis) and gray bats (M. grisescens) thatnate there from human disturbance. Hopefully, the protection of this cave from disturbance during the hibernation period will result in anase in the numbers of M. sodalis, M. grisescens, and M. keenii that hibernate there.LITERATURE CITEDBARBOUR, R.
