The Green Oakblue (Arhopala eumolphus maxwelli)
The male Green Oakblue is one of three extant species of the genus Arhopala that features metallic green uppersides instead of the usual purple or dark blue uppersides that are more common amongst the species in the genus. The female of the Green Oakblue, however, features purple uppersides with broad black borders on both wings (shown above). The species was re-discovered in Singapore some time in late 2007 in a patch of forested area near a reservoir park. The full life history has been documented here.

The underside of the Green Oakblue is typical Arhopala - brown with the usual striations. One of the key distinguishing markings is the post-discal spot in space 4 on the forewing being out of line with the spots above and below it. The species is considered moderately rare, but is very local and at times, several individuals may be spotted together. This pristine female Green Oakblue was shot by young ButterflyCircle member, Jonathan Soong.
