Summary
Agriades glandon, commonly known as the Arctic blue or Glandon blue, is a butterfly of the Lycaenidae family found across Eurasia and North America, characterized by its distinctive wing coloration and habitat preferences.
Physical Characteristics
Wingspan of 17–26 mm; males have silver-coloured to steely blue or pale shining blue upper wings with brown edges; females have almost entirely brown upper wings with a slightly bluish basal region; both sexes have white-rimmed black dots on the forewing underside and striking white spots on the hindwing underside, sometimes with orange-colored dots.
Identification Tips
Distinguishable from other bluish species in Europe by geographic variability in wing patterns; confused with Aricia nicias and Agriades pyrenaicus in overlapping ranges.
Habitat
Arctic tundra, subarctic and subalpine forests, mountain meadows, and bogs.
Distribution
Found in North America from Alaska to Newfoundland, south through the mountains to Washington, northern Arizona, and northern New Mexico. In Europe, found in the Pyrenees, Alps, and far north, including parts of Russia such as Siberia and Kamchatka.
Diet
Larval food plants include Androsace species, Soldanella species, Oxytropis campestris, and various Saxifraga species.
Life Cycle
Adults typically fly from mid-May to September, depending on location.
Evolution
Taxonomically lumped with the genus Plebejus; geographic variances noted among subspecies and confusion with similar species.
