Lasiopogon terricola. Another shot taken in the northeast by Michael Thomas. Lasiopogon is a large group in the east (even larger in the west) now that Rob Cannings has further defined the group in 2002 (see the Systematics of Lasiopogon from the Royal British Columbia Museum). Seven of the fourteen species below were added by Cannings in 2002. Some of them are either extremely rare or extremely limited in distribution or both. I have not yet seen a live member of this genus and photographs are not common. They are a spring dominant group (mostly March to May) and indeed among the first robbers out in the northeast.

None had been found in Arkansas until April 2006 when Norm Lavers found one in NE AR in the Ozarks. (See below discussion and photo.) Final species identification is still pending on this. None are known to occur in Florida. And even stranger -- none are known from Texas though one is found in Oklahoma. These robbers favor deciduous streamsides in the east. And obviously from the above photo L. terricola favors a nice sandy embankment. This likely makes them subject to rapid reductions in distribution with growing stream ecology problems in the east and limited distribution overall. Any specimens collected in the east are of interest. All photos are probably scientifically important, even shots of the widespread northeastern species.


Eastern species are:

L. appalachensis Cannings 2002 [WV, KY, TN] Recorded in May only.

L. chrysotus Cannings 2002 [TN] Known from only two males.

L. currani Cole & Wilcox 1938 [Northeast and VA, NC, SC, GA]

L. flammeus Cannings 2002 [NC] Known from only three males.

L. marshalli Cannings 2002 [VA] Common in Virginia river habitat. Likely other Appalachian areas.

L. oklahomensis Cole & Wilcox 1938 [AR, OK] Oklahoma in Caddo, Cleveland and Payne counties. Now also in AR.

L. opaculus Lowe 1874 [Widespread]

L. piestolophus Cannings 2002 [AL] Known from one male and one female, Coastal plain.

L. schizopygus Cannings 2002 [GA, MS, NC, SC] Includes the former L. carolinensis.

L. shermanni  Cole & Wilcox 1938 [SC, NC] Last specimen collected in 1957.

L. slossonae Cole & Wilcox 1938 [Northeast to VA, OH]

L. terricola (Johnson 1900) [Northeast to IN, VA, OH]

L. tetragrammus Lowe 1874 [Northeast]

L. woodorum Cannings 2002 [Northeast]

This is confirmed now as Lasiopogon oklahomensis. I have seen Edward's specimens from the same area as this shot was taken which was near the Buffalo River in May 2007. We are still trying to determine if Norm's male from the Gunner Pool area is the same. There is one at the museum at Fayetteville and a male and female are off to Dr. Cannings in BC. He did finalize this as oklahomensis with some slight regional color variation. This is the first of the genus in our state.
