To recognize leaves that are attacked, requires very little skill. 
(They may be attacked by either this or the succeeding species). 
They are slightly drawn together, and present a contorted appear- 
ance. 
The holes made in the leaves are easily seen, and often a further 
indication of the presence of the insect is that the holes are woven 
over with silk which prevents ants and other natural enemies from 
gaining an entrance. 
The length of the time occupied from the hatching of the egg to 
reach the adult larval state is rather variable, but three weeks may 
be taken as a fair average. When adult the larva coils a portion of 
the leaf over itself and pupates. The colour of the pupa is light 
brown at first, later attaining a darker colour. Length 10-13 mm. 
In about eight days the adult insect emerges. 
Larva. — Greenish on the upper side; somewhat sage coloured in 
some specimens. Head and first thoracic segment hard, shining 
jet-black. A series of small tubercles running in four longitudinal 
parallel lines on the dorsal surface. Three thoracic legs, first and 
second of same colour as the head, third semi-transparent, black at 
apex. Four abdominal feet one pair of,elaspers. Single long hairs 
spring from the body. Length when adult about 15 mm. 
Moth . — The moth is a very variable insect in colour, descriptions 
are given of the two commonest forms. 
1. Fore wing; upper side. — Ground colour rich black purple or 
brownish. Thickly scaled; fringe of the outer margin brownish, at 
apex black. Irregular blotches of rich brown and yellow distributed 
over the wing. 
Hind wing; upper side. — White at costal margin, yellow before 
apex, greyish posteriorly. 
Under side of fore wing white on inner margin. Costa with two 
yellow spots, one half way along, and one near apex. Anterior 
portion of hind wing on under side suffused with yellow, remainder 
greyish. Head and thorax thickly scaled with rich purple scales. 
Antennae of same colour as head at basal joints, remainder yellow 
palpi brownish or yellowish; four posterior legs yellow, anterior 
pair darker. 
2. Fore wing ; upper side. — Red brown. Black and light yel- 
lowish brown striae. A dark spot on costal margin of fore wing. 
Markings on upper side of hind wing same as in the other form. 
Fore wing; under side, — Apical and outer margin yellow extend- 
ing as far as discocellular. Basal portion of costa yellow. The 
black irregular striae more distinct than on the upper side. Remain- 
der of wing dull grey. 
Hind wing ; under side. — Costal margin pale yellow, becoming 
darker towards outer margin. Remainder of wing dull grey. 
Exp. 20 mm.
