Plebejus idas lotis (syn. Lycaeides idas lotis, Lycaeides argyrognomon lotis, Plebejus anna lotis
This butterfly is very rare with low population densities. This mainly due to human disturbance effecting and creating changes in vegetation. According to the Nature Conservancy, it is critically endangered. It is ranked as Ti, critically imperiled (Zverev, 2021). In the summer of 2014, a fire in Vastmanland in South Central Sweden affected an area of 13,100 ha. After the fire the Idas Blues along with other species increased in numbers. This is presumed to be because of an increase in larval host plant abundance.[6]
Distribution
This species can be found in most of Europe (except parts of Spain, southern Italy and the United Kingdom),[7] in the northern regions of the Palearctic (Siberia, mountains of South Siberia and Yakutia) and in the Nearctic realms.[8][2]
Habitat
It usually inhabits grassy flowery areas, mixed evergreen forests and wet meadows up to alpine levels,[7][9] at an elevation of 200–2,100 metres (660–6,890 ft) above sea level.[10]
Description
Plebejus idas has a wingspan of 17–28 mm.[1][10] 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.[9]
This species is very similar to the Silver studded blue (
Biology
The species flies in a single brood from June to August depending on location. Second-stage of the caterpillars overwinter. Male butterflies will patrol and find plants to host the female butterflies. The female butterflies will lay the eggs on the host plant stems or debris (Bálint, 2020).
