(Cranberry Blue)

Conservation Status

Population Analysis

  • For the 844,129 species in the Class Insecta (Insects), we average 3.71 observations each in our database; for the Cranberry Blue, we have 1,434 observations. Compared to other species in this Class, this species is extremely common.
  • A two-sample t-test can be used to determine whether the trend in observations of the Cranberry Blue is the same as the trend in observations of Insecta. Is this species just as common, as a proportion of all observations, as it once was? The answer is yes, changes in observation rate of this species do not significantly differ from changes in observation rate of its Class.

Physical Description

Subfamily Polyommatinae:

Blues are tiny to small butterflies of the Family Lycaenidae. Distributed worldwide, they are most diverse in Southeast Asia, tropical Africa, and northern temperate regions. Most of the nearly 50 North American species are found in the west. Adult males are predominantly blue above, due to reflected light rather than pigmentation. Some males and most females are largely brown above. Below, wings of both sexes are usually gray-white with black spots or streaks. Adults in some genera (Euphilotes, Lycaeides, Plebulina, and Icaricia) have more or less prominent orange submarginal bands on their hindwings. Most adults are found near their host plants, and they do not fly long distances, though some tropical and subtropical species undertake long migrations. Adults visit flowers for nectar. Males frequent moist sand and mud, and females lay eggs singly on host plant leaves or flowers. As caterpillars, they secrete sugary secretions that attract ants, and caterpillars of some species are raised in ant nests. Blues usually overwinter in the pupal stage.
