THE GREEN HAIRSTREAK 
271 
blunt round anal extremity, which bears a few minute anchor¬ 
shaped cremastral hooks. The pupa is not attached to any¬ 
thing, being merely spun loosely over with a few silk threads. 
The ground colour of the pupa is amber-brown checkered 
and speckled with black, some are much more heavily marked 
than others, giving them a very dark appearance. Except 
for the wings and limbs, the whole surface is densely covered 
with finely-serrated spines of a dark brown colour. 
The pupal state lasts about ten months ; i.e. from about the 
middle of July to the middle of the following May. 
Imago. The sexes may be readily distinguished by a small 
oval spot of black androconial scales at the end of the cell 
of the fore wing of the male, characteristic of freshly-emerged 
specimens ; in captured examples this patch is usually pale 
greyish, due to the loss of the black plumose scales. 
In freshly-emerged individuals the ground colour is a rich 
bronze-brown, with a greyish bloom over the base. At the 
anal angle of the hind wing the fringe forms a short tail-like 
tuft of black scales, and there is a small edging of dull orange 
along the margin from the anal angle. The fringe of the fore 
wing is dusky, and that of the hind wing is white spotted 
with black. 
The under side is green, except for the inner marginal area, 
which is an iridescent greyish-fulvous. A series of white 
spots or streaks extends across the wings, usually two or 
three on the fore wing and a few on the hind wing ; sometimes 
these are almost connected and produce a complete line across 
the hind wing. 
Life of Imago. This little butterfly is apparently long-lived 
in comparison to the other Hairstreaks. I have kept 
specimens in captivity for six weeks. 
Aberration. There is considerable aberration in the develop¬ 
ment of the white markings on the under side, ranging from 
a complete row across both fore and hind wings to an entire 
absence in others. The latter is known as ab. inimaculata, 
Fuchs. Specimens from northern districts have generally the 
most strongly-developed markings. The green varies from a 
dull ochreous-green to emerald. Occasionally, the upper 
surface is more or less smoky-grey, and specimens now and again 
occur with one or more wings blotched with pale ochreous.
