areas on- Cal ifornia State Park lands, lands near Jackson State Forest and private lands in coastal Mendocino and Sonoma Counties but did not 1 oca t e addi tional col oni es of the butterfly. Areas examined were historical c,ollection sites and sites that appeared to provide the habitat of the lotis blue butterfly. Many of the col lection sites are either in, or on the periphery of, the Pygmy Forest. However, these and other surveyed sites lacked the assemblage of bog plants, such as sphagnum and sundew, and the probable larval foodplant, Lotus formosissimus, characteristic of its present local i ty. Until the larval foodplant is positively determined, it may be impractical to continue searching for additional sites. Life History Little is known about the 1 ife history of the lotis blue butterfly, thus information is extrapolated from closely related species. Because the larval foodplant is not confirmed, no rearings of this butterfly have been conducted. Museum records suggest that the butterfly has a protracted single generation (univol tine), with adult flight occurring from mid-April to early July. Most collection records are frm mid-May to mid-June. Other Nearctic races of - L. argyrognomon are also univol tine (Downey 1975). It is generally believed that eggs are laid during the adult flight season and newly hatched larvae begin feeding immediately. The second instar larvae begin diapause (resting stage during larval development) , which is broken sometime duriqg the fol lowing spring.
