It merely bites its way out of the flower after having eaten the ovary, 
and travels to the next flower. It is of very retiring habits, and is 
rarely seen until full fed, when it comes outside to spin. It spins a 
slight pad, to which it securely fastens itself by its prolegs. After 
securing itself it remains motionless except for a regular and convulsive 
movement which ultimately enables it to split the larval skin. The 
larvae producing these imagines were first obtained about the middle of 
August. 
As regards description, it is a typical “Plume” larva, being 
slightly and gradually attenuated from the head to the anal segment. 
The appearance presented is decidedly like that of tlalias prasinana 
before the first moult. The colour is apple green with black and white 
hairs. Spiracles are present on segments one, and four to eleven, and 
are very high up on the sides. They are black in colour. The seg¬ 
mental divisions are not very pronounced, though segments one to five 
show a tendency to divide into two annulets. 
The head is inserted in the first segment and is carried well under 
it. Mandibles are pale brown, the remainder apple green blotched 
with brown, ocelli black. A few white hairs are scattered on its 
surface. 
The true legs are green, tipped with brown. The skin is shiny and 
shagreened all over. It is clothed with two distinct classes of hair. 
There are a number of long hairs fitted into sockets, which are white 
on the lower parts of the larva, and brownish grey above — these have 
all the appearance of sensory setae. The other class are clubbed hairs, 
and are very short, arising direct from the skin, some of these being 
black and some white. The black hairs are almost confined to the 
dorsal area and the area below the spiracles, the remainder of the larva 
being occupied by white hairs with a very few black intermixed. 
There are, however, usually a pair or more of the black hairs at the 
base of each sensory seta. The prolegs are green with the hooks very 
dark brown, almost black. 
The dorsal line is dark green, due to the pulsating dorsal vessel; 
it is bordered with whitish, and beyond the whitish line is a darker 
green band. The lownr part of the body is dark green. 
The pupa is at first bright green with the wing and leg cases 
darker green. As maturity approaches the pupa takes a very much 
greyer tinge and especially so on the wing cases. The colour seems to 
be entirely due to the internal contents as the pupal skin is not 
pigmented. There are eleven segments and the usual thoracic plates. 
The four posterior segments are tinged with brown, the ultimate and 
penultimate segments being almost a light sienna brown. There is a 
conspicuous dorsal stripe of dark green, which is slightly wider in the 
centre of each segment. The 8th, 9th, 10th and 11th segments 
(counting from the anal segment) bear ridges each side of the dorsal 
line, which gradually converge until they meet the thoracic plates, 
where they are very pronounced and separated by a deep fissure. The 
spiracles have the appearance of green blotches and there is a waved 
sub-spiracular band, also dark grey-green abdominal band each side of 
the ventral line. The wing cases are deeply grooved following the 
neuration of the perfect insect. They are produced to form a case for 
the posterior pair of legs. The leg case frees itself at segment seven 
xviii.
