Lycaenidae<br />
Male<br />
It has a minute tornal tail and a circular lobe at the anal angle which acts as a false eye<br />
at the back. The metallic indigo blue on the upper side <strong>of</strong> the male fades in to black<br />
towards the forewing margin, varying according to the viewing angle. The pale brown<br />
circular sex brand on its hind wing is usually concealed by the forewing. The female<br />
is a much lighter blue with a purple wash. The underside looks similar in both sexes.<br />
The background varies from pale brown in the dry season form to dark grayish brown<br />
in the wet season form. Its distal bands are much broader and more irregular than in<br />
its relatives. The cell end patch <strong>of</strong> the hind wing usually touches the distal band. It<br />
has ‘eye spots’ both at the tornus and the lobe and black and blue scales in between.<br />
The fast flying Indigo Flash prefers to bask at around 2.00 pm in the afternoon under<br />
beams <strong>of</strong> light that filter down through trees to the shrubbery. Usually 2-3 individuals<br />
participate in this activity together. It is fond <strong>of</strong> feeding on nectar from shrubs.<br />
It is found in forests and verdant home gardens. Though it is distributed throughout<br />
the low country, it seems to be more abundant in the wet zone than in the dry zone.<br />
It is not a regularly observed butterfly.<br />
The circular lobes at the anal angle <strong>of</strong> the hind wings act as false eyes, deceiving<br />
predators that come up from its behind. The eyes are distinctly large. The upper side<br />
<strong>of</strong> the male’s hind wing and basal parts <strong>of</strong> the forewing are deep shiny red. The rest<br />
<strong>of</strong> the forewing is black in colour. The hind wing veins are thinly marked in black.<br />
The upper side <strong>of</strong> the female is completely dark greyish brown with barely exposed<br />
forewing cells in a much darker hue. The underside is similar in pattern in both sexes,<br />
with a purplish sheen on males. Its distal bands are very broad and only merely<br />
marked in white outlines without any distinct separation in colour in relation to the<br />
background. Its black tornal spot is situated further inward towards the base, and is<br />
<strong>of</strong>ten completely ringed in orange in contrast to only a capping in Rapala species.<br />
The very fast flying Cornelian prefers to feed on compound flowers such as<br />
Chromolaena odorata (fmdäisx[af[daurx). It is <strong>of</strong>ten seen flying around small shrubs.<br />
This is a migrant species.<br />
It can be seen throughout the low country in scrublands and amidst other open<br />
vegetation but is not a frequently seen species.<br />
