HAWK-MOTHS. 49 
is bluish; seven oblique stripes, of a pale yellowish-white 
color, are found on each side of the worm, the last one 
of a brighter yellow than the others, and extending to the 
base of the horn (Fig. 52). The caterpillar enters the earth 
for pupation and changes to a chestnut-brown smooth 
pupa, with a short terminal spine. 
The moth (Fig. 53, Plate VIII) appears from May toJuly, 
but chiefly in June. It is a very handsome insect. Its body 
is fawn-colored; on the top of the thorax is a chestnut- 
colored stripe, and on the abdomen a dark-brown line. The 
front-wings are fawn-colored, or rich brown, clouded and 
striped with two broad bands of lilac-gray; the hind-wings 
are rose-colored in the middle, with a brownish patch at the 
tips, crossed by two or three short whitish lines, and having 
near the inner angle a black spot with a pale blue center. 
The antenuze of the male are pectinated beneath. The 
moths measure with expanded wings about three inches 
across. 
This and some other closely allied moths have very 
short, scarcely visible tongues, and their fore-wings are 
generally scalloped on the outer edge. When at rest, the an- 
terior portion of the hind-wings projects beyond the {ront- 
wings, and the abdomen is usually turned upwards. In this 
position the highly-colored eye spots are no longer visible, 
and the insect resembles very closely a dead leaf. 
This insect is by no means a rare one in Minnesota. Its 
larva is found on the apple tree and also on the plum and 
wild cherry, but it pre'ers the smaller oaks. It causes but 
little damage to our {fruit trees. The caterpillars are not 
readily seen, as they assume during the day a rigid and 
-sphinx-like position, but they make their presence readily 
visible by defoliating whole branches. 5
