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 lacturnus is
found from India east to China, Korea and Japan,
south through Thailand, West Malaysia, Sumatra, Borneo, Sulawesi and
the smaller islands west of the Wallace Line, and down to the north
coast of Australia.
On the upper
surface of the wings the male is violet-blue, with blackish borders
which vary in width according to location and subspecies. The female
is entirely brown, except for the orange lunules and black spots at
the tornus of the hindwings.
The short tail is present in both sexes, but is often lost after a
few days of activity.
The underside is
pale silvery-grey, with a bright reddish-orange blotch at the
hindwing tornus, and a series of dark grey marginal and submarginal
tiny butterfly, which is also known as the Tailed Cupid, is found in
disturbed habitats including forest clearings, plantations, parks,
gardens, and along roadsides and riverbanks. It occurs at all
elevations between sea level and at least 1600 metres.
The eggs are pale green, round and flattened.
They are laid singly on the flowers and pods of the foodplants which
include several Desmodium and
Trifolium species, and undoubtedly also
on other genera of low-growing herbaceous Fabaceae.
The caterpillar is
woodlouse-shaped and slightly hairy. It is green in colour with
small patches of reddish-brown dorsally.
The chrysalis is
pale translucent green, marked with a double row of tiny black dots
along the back, and covered in shortish soft hairs on the head,
thorax and lower abdomen. It is formed among the fruit pods of the
are usually seen singly, or in mixed aggregations
with other Polyommatines, mud-puddling on damp patches of ground.
Both sexes visit flowers, showing a preference
for small white or blue species rather than the more showy plants.
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 short proboscises.
When feeding, either on the ground or at flowers,
the butterflies hold their wings erect, but they can also be seen
basking on foliage with their wings held half open.
