Plebejus itas lotis (syn. Lycaeides idas lotis Lycaeides argyrognomon, Plebejus argyrognomon[3]) is a critically endangered butterfly native to Mendocino County, California,[1] with sightings in Sonoma and Marin counties. It has been listed as an endangered species since June 1, 1976,[2] but has not been sighted in the wild since 1994. DistributionThis species can be found in most of Europe (except parts of Spain, southern Italy and the United Kingdom),[6] in the northern regions of the Palearctic (Siberia, mountains of South Siberia and Yakutia) and in the Nearctic realms.[3][4] HabitatIt usually inhabits grassy flowery areas, mixed evergreen forests and wet meadows up to alpine levels,[5][10] at an elevation of {{convert|200|-|2100|m}} above sea level.[11] DescriptionPlebejus idas has a wingspan of 17–28 mm.[6][7] This species is quite variable in colors and markings. The upperside of male's wings is iridescent blue, while it is brown with orange submarginal spots in the females. The underface of the wings is greyish with black spots and it shows a thin black line and small dots along outer margin. Along these margins are also present a rather large orange band with blue spots.[8]This species is very similar to the Silver studded blue (Plebejus argus) and to the Reverdin's blue (Plebejus argyrognomon).[5] The forelegs of male of Plebejus idas lacks a hook which is present in Plebejus argus.[7] BiologyThe species flies in a single brood from June to August depending on location.[8] The larvae feed on Calluna vulgaris, Vaccinium uliginosum, Empetrum nigrum and various Fabaceae species (mainly Cercis siliquastrum, Melilotus albus, Lotus corniculatus, Cytisus, Genista tinctoria, Trifolium pratense, Chrysaspis campestris, Astragalus alpinus and Anthyllis). They are usually attended by ants (Lasius and Formica species).[4][9] Second-stage of the caterpillars overwinter.[8] GalleryReferences1. ^"Lotis Blue Butterfly", Arcata Fish and Wildlife Office 2. ^1 "Lotis Blue Butterfly", Xerxes society Profile 3. ^Jim P.
