The genus Everes
comprises of 7 species distributed variously across North America,
Europe, Asia, the Oriental region and Australia. It is regarded by
some authorities as a subgenus of Cupido
which consists of a further 11 Eurasian species.
Everes and Cupido
males are dark brown overlaid with metallic blue or violet scales.
In amyntula and some other species the
blue covers almost the entire wing surface. In others such as
minimus there is only a light dusting
of blue over the basal area.
In females the amount of blue is usually reduced.
The underside of
all species is pale silvery-grey, with a series of dark grey
marginal and submarginal dots and dashes.
Everes have small orange cubital spots on the underside
hindwing, but these are absent in Cupido.
There are 2 Everes
species found in North America - comyntas
which is found in the eastern states of the USA and south to
Ecuador; and amyntula which is
endemic to the
western states of the USA.
species is usually found in disturbed or eroded habitats including
mountain scree slopes, fields, meadows, dunes, riverbanks, and along
wide sunlit forest trails.
The eggs are white, round and flattened. They are
dotted in two's and three's on the sepals, petals, leaves or stems
of the foodplants. These include Astragalus,
Lathyrus and various other genera of
The larva is
woodlouse-shaped and slightly hairy. It occurs in several colour
forms - whitish, buff, pale brown or pale green. It has a dark
dorsal stripe, either side of which is a series of dark oblique
dashes. The pupa is pale buff, with a broken black dorsal stripe and
a series of dorso-lateral black spots. It is usually formed on the
underside of a leaf, attached by the tail to a silk pad, and secured
with a silk girdle around the waist.
are usually seen singly, or in mixed aggregations
with other Polyommatines, mud-puddling on damp patches of ground or
visiting dung. Both sexes visit a wide variety of flowers. They tend
to spend a long time on each plant, walking about over the flower
heads as they probe different parts of the nectaries with their
proboscises. When feeding they hold their wings erect or half open.
