Summary[edit] Description: Hexton day-time Hello all. I had an hour's mooch around Hexton Chalk Pit and was pleasantly surprised to see a lot of Lepidoptera on the wing in the warming sunshine. The temperature was around 16 degrees but somehow felt warmer out of the stiff NE breeze. I scoured all over the small reserve and saw plenty flying, but the hard bit was going to be photographing them! I noted Dingy Skipper everywhere, they were the commonest Lepidoptera flying with Small Purple-barrred and Pyrausta nigrata a close 2nd and 3rd. I also saw my first ever Green Hairstreak, my god they are hard to photograph. Also Burnet Companion, Pyrausta aurata and Elachista argentella were found but no Mother Shipton noted today, which I have seen here before. Other Butterflies included Red Admiral, Orange-tip and Brimstone. On the Bug and Beetle front there were lots of Bishop's Mitre Shield-bugs and some lovely large Elateridae, Agrypnus murinus. All in all a blooming successful walk around!

A Duskywing that seems to most closely match Erynnis persius. This was a "hilltop" location favored by E. persius males. There is a sharp contrast in the gray forewings and gray-brown hindwings. The multiple forewing spots are usually described as white but may be appearing yellow here because of the intensity of the setting sun. The hindwing fringe is normally described as creamy white but here again appears yellow. Forewing fringe here also appears light/yellow which differs from most descriptions.The antennal club should be hooked. While difficult to see, at high magnification that can be seen to some degree here. This butterfly is visiting Arrowleaf Balsamroot, Balsamorhiza sagittata.May 9, 2012, Mile High FS property, Olympus foothills, Salt Lake County, Utah, approx. 5160 ft. elev., fixed length lens (not zoom; no adjustments).
