Thecla iri s, Godt. 
This larva is yellowish-green, with two interrupted dorsal lines 
and a pale green line on each side; also eight oblique pale green 
streaks on each side. Feeds on Vaccinium. 
Chrysalis pubescent with two obscure longitudinal lines. 
Thecla niphong, Hub. 
This larva, when young, is a pale transparent green, with four 
longitudinal white stripes; a white lozenge-shaped patch on the 
eleventh segment; body covered with short brown hairs. When it 
is full grown it is of the same deep green color as the leaves on 
which it feeds. A yellow stripe along the middle of the back and a 
white stripe on each side; a narrow white line close to the feet. 
Head brown. 
Chrysalis thick, grayish, with two rows of small blackish spots: 
outside of these a row of more conspicuous rust-red ones. Found 
in June on various species of Pine.

Thecla titus, Fab. 
The young larva is rosy-red on the upper side, sparsely covered 
with long hairs; under side, feet and pro-legs yellowish; head small, 
brownish-black. As it grows it gradually loses its rosy hue and 
turns greenish. When full grown it is dull green above, with a 
yellowish tinge anteriorly. The hairs are very short and thickly 
sprinkled over the body, each arising from a pale yellowish, slightly 
raised dot; on the back a streak of dark green showing through the 
semi-transparent skin from the second to the fourth segments; a 
row of irregular pinkish patches and spots on the back; second 
segment constricted; a wide ridge on the back from the third to the 
tenth segments, behind which the body is suddenly flattened; under 
side yellowish-green, sparsely covered with fine brownish hairs; feet 
and pro-legs greenish, semi-transparent. Head small, bilobed, 
shining black, with a streak of dull white across the front above 
the mandibles, which are reddish-brown. Length 0.70 inch. Found 
in May on Wild Cherry, Wild Plum, Oak, and Euptatorimn coelesti- 
nium the next February. 
In its younger stages the larva is white, and so near the color of 
the buds on which it feeds that it is difficult to distinguish. It 
feeds on the inner part of the bud, cutting away the surface on one 
side and making a hole into which it thrusts its head, elongating 
its neck as it proceeds until it has devoured the whole of the inside, 
leaving only the shell. On the eleventh segment are two little 
openings, from which are protruded, at the will of the caterpillar, 
two little transparent hemispherical vesicles from which issue a 
drop, probably a sweet fluid, as it is eagerly watched for and 
swallowed by the ants in much the same manner as they take the 
lioney-dew from the Aphides. 
The pseudargiolus and violacea are the different broods of the 
same species, the latter being the spring brood and the former the 
fall, the eggs of one hatching the larvae of the other.
