Ce 
ings and has a wingspread of 100 to 150 mm. Full-grown larvae | 
are heavy-bodied and about 100 mm. long. The head is orange | 
yellow with green sides; the body, pale green to dark green or 
reddish purple and covered with long, whitish hairs. Adults ap- 
pear during June and July and. larvae are present from July to 
October. Winter is spent in the pupal stage in the ground, and 
there is one generation per year. 
Eacles imperialis pini Michener feeds on white and jack pines 
in New York, Michigan, and southern Canada. The adults are 
smaller than those of the imperial moth and have dark markings | 
of pink to pinkish-brown. Markings on the surfaces of the wing | 
are also heavier than those of the imperial moth. Adults are 
present from mid-June to mid-July. | 
FAMILY CTENUCHIDAE 
Lymire edwardsu (Grote) has been recorded feeding as larvae 
on the foliage of banyan and Fcus trees in Florida. The adult is 
a Sluggish, bluish gray to purplish gray moth, with blue and . 
plumose antennae. The thorax is orange-red beneath, the abdo- 
men white beneath and blue above. Larvae are somewhat whitish 
with a dark tuft of hairs on the thorax. When touched, they usu- 
ally flip from the leaf to drop to the ground on silken threads. 
This species is occasionally destructive of shade or ornamental 
trees (283). | 
FAMILY ARCTIIDAE 
TIGER MOTHS AND ALLIES ~ 
This is a large family of stout-bodied moths with moderately 
broad wings. In general they are moderate in size and have broad | 
heads and pectinate or ciliate antennae. Many species are marked | 
with brightly colored spots and stripes. All are night fliers and are 
attracted to lights. They usually fold their wings roof-like upon | 
the abdomen while at rest. The larvae of most species are clothed | 
with dense clusters of hairs. In some species, certain of these | 
clusters are larger and longer than others, causing the larvae | 
to resemble those of the tussock moths in the family Lyman- 
triidae. The hairs of certain species are irritating. The majority 
of species prefer the foliage of low growing plants. A few feed 
on the foliage of trees and shrubs. 
The hickory tussock moth, Halisidota caryae (Harr.), occurs in 
southern Canada and south in the Eastern States to North Caro- 
lina. The larvae feed on the foliage of a wide variety of deciduous 
trees and shrubs including walnut, butternut, hickory, birch, elm, 
black locust, basswood, and aspen. Walnut, butternut, and hick- 
ory appear to be preferred. Adults are light brown or buff in 
color, with numerous silvery white spots on the forewings, and 
they have wingspreads of about 50 mm. Full-grown larvae are 
grayish-white and about 37 mm. long. The body is clothed with 
short, spreading tufts of grayish-white hairs. There is a row of 
black tufts on the first eight abdominal segments and pairs of
