Season Summary 2009 Zone1 Far North Alaska, Yukon, Nunavut, and Northwest Territories Coordinator: Kenelm W. Philip Contributors Cited: ALS : Alaska Lepidoptera Survey CSG : Cris S. Guppy TH2 : Takashi Hino JXK : James J. Kruse KWP : Kenelm W. Philip General Comments: No new localities were visited in 2009, but some old ones were sampled and reported. Note regarding the Alaska Lepidoptera Survey: Trips were made to km 130.5 on the Dempster Highway (YT) and the Toolik Lake vicinity (North Slope, AK) for live close-up photographs of two butterfly species in June. Butterfly numbers were down at both sites compared to my previous visits. Two trips in July to southcentral Alaska were failures despite sunny weather. The Bonanza Creek Experimental Forest, and the Chena Flood Control Project, were checked regularly throughout the summer when the weather permitted. Collections by ALS volunteers were carried out in the Bristol Bay area (Round Island and King Salmon). YUKON TERRITORY Weather: Similar to Alaska, resulting in a poor butterfly season.
