DescriptionThe Puget blue is a small blue and grey butterfly with a wingspan of around {{convert|1.8|in|cm}} in the family Lycaenidae. The male has dorsal wings that are a silvery blue with a wide dark margin. The female is grey brown with diffuse blue patches at the base of the wings.[1] The range of this species spans from Vancouver Island and the Olympic Mountains in alpine to subalpine habitat to the lowland prairies of the South Puget Sound. Conservation statusAt this time, the Puget blue has not yet been designated endangered or threatened by the federal government, but it is a candidate species for restoration in the state of Washington. Populations in the prairies have declined due to the loss of prairies as well as the encroachment of woody vegetation such as Douglas-fir (Pseudotsuga menziesii) and Scotch broom (Cytisus scoparius). ThreatsScotch broom out-competes the host plants of this butterfly species and as a nitrogen fixer it alters the natural nutrient balance in the soils. Because many prairie species, such as their host plant, the lupine (Lupinus lepidus), have adapted to thrive on much lower nutrient levels the increased nutrient loading greatly inhibits the lupines ability to thrive.[2] The subalpine populations have increased as logging activities have cleared land allowing the expansion of their host plant the lupine.[1] The biggest threat to the subalpine populations is climate change, while the prairie populations are most threatened by habitat loss and fragmentation. Land management techniques used to maintain prairies such as controlled burns, can either help or hurt populations of native butterflies. If timed correctly controlled burns can greatly increase that year's lupine crop, giving the Puget blue a better chance of success.[1] References1. ^1 2 {{cite journal|last=Flackenstein|first=J.|title=National Heritage Program, Puget Blue Species Fact Sheet|journal=Washington Department of Fish and Wildlife|year=2006}} {{Taxonbar|from=Q5985055}}2. ^{{cite journal|last=Grosboll|first=D.|title=Three endangered taxa from Puget lowlands: Polites mardon, Icaricia icarioides blackmorei, Euphydryas editha taylori |journal=MES project Everegreen College|year=2005}} 2 : Icaricia|Butterflies of North America |
