The genus Udara
comprises of about 40 species found variously from India and Sri
Lanka to China, Japan, Malaysia, the Philippines, Indonesia, New
Guinea and north-east Australia. There is also a single species
blackburnii which is endemic to Hawaii.
The upper surface
of the wings of all species are very pale silvery blue, with
blackish margins that are broader in the female than in the male.
The pattern of black spots and grey markings on the silvery grey
underside is found in several other genera including
Celastrina so close attention to the configuration of the
markings is essential when identifying these butterflies.
Udara dilecta is found in India,
Bhutan, Laos, Cambodia, Thailand, China, West Malaysia, Sumatra,
Borneo, Sulawesi and New Guinea.
This butterfly is found in open forested habitats
at elevations between about 500-2000m.
larvae are known to feed on Castanopsis
( Fagaceae ).
Males are usually
seen either singly or in two's and three's amidst mixed aggregations
of mud-puddling Polyommatines.
