Amorbia humerosana Clemens occurs from coast to coast in southern Canada 
and in the Northeastern States south to Pennsylvania. Its hosts include a wide 
variety of tree species, both coniferous and deciduous. Adults are light gray and 
have wingspreads of about 25 mm. Larvae are light green except for light-brown 
heads. 
Sparganothis acerivorana (MacKay) occurs in southern Canada and the Lake 
States. In Canada it feeds on several hardwoods, mostly sugar and red maples, and 
also on young Scotch and red pines. In the Lake States, it usually feeds on sugar 
maple. The adult is reddish yellow with reddish-brown spots and has a wingspread 
of about 25 mm. Full-grown larvae are yellowish green and about 21 mm long. 
Winter is apparently spent in the egg stage, and hatching occurs during May of the 
following spring. Each larva rolls a leaf in which to rest and from which it moves 
out to feed. Pupation occurs inside the roll. 
Defoliation by this species was an important factor leading to the development of 
maple blight, a condition responsible for the deterioration and death of large 
numbers of sugar maple trees in Wisconsin (483). 
Sparganothis pettitana (Robinson) occurs in southeastern Canada and south and 
west to Florida and the Mississippi River Valley. The larvae are solitary leafrollers 
on various hardwoods, especially basswood and maples. The adult is lemon yellow 
and has a wingspread of about 22 mm. The forewings are sometimes marked with 
two oblique lines of light-brown scales, and the hindwings are white. Full-grown 
larvae are dull, yellowish green, with reddish-brown heads and brown to blackish 
cervical shields. 
Sparganothis sulfureana (Clemens) has been observed feeding in the tips and 
shoots of small red pines in Canada and in the terminals of loblolly pine seedlings in 
Georgia. Willow, honeylocust, apple, and cherry are also attacked. S. reticulatana 
(Clemens) occurs over about the same range as S. sulfureana. It feeds on white ash, 
maple, bigtooth aspen, and paper birch. S$. diluticostana (Walsingham) occurs 
commonly on oak in New Jersey and Maine. It has also been recorded feeding on 
white ash and paper birch in southern Canada. S. fristriata (Kearfott) occurs fairly 
commonly on jack pine in southern Ontario. It probably occurs in the Lake States 
also. 
The genus Pandemis contains several species that attack a wide variety of 
hardwoods in eastern North America. P. /Jamprosana (Robinson) feeds on beech, 
paper birch, red and sugar maples, oak, elm, basswood, ironwood, and sassafras 
from Maine to New Jersey and in southern Ontario and Quebec. The threelined 
leafroller, P. /imitata (Robinson), occurs from coast to coast in Canada. It has also 
been recorded from Maine, Pennsylvania, Georgia, Illinois, and Arkansas. Its hosts 
include paper birch, willow, oak, basswood, elm, boxelder, alder, and cherry. 
Archips rosanus (L.), an introduced species, occurs in southeastern Canada, 
British Columbia, and from New England to the Lake States. The larvae are general 
feeders on a number of deciduous species. Privet appears to be especially attractive. 
Adults are dull light-brown to olive-brown and have wingspreads of about 20 mm. 
Full-grown larvae are dull green and about 18 mm long. The larvae tie together two 
or more leaves at the tips of twigs or branches and feed on them during May and 
June. 
The uglynest caterpillar, A. cerasivoranus (Fitch), occurs from coast to coast in 
the Northern States and southern Canada. Its preferred hosts are common 
chokecherry and black cherry, but it may also be found on a wide variety of other 
hardwoods. The adult is dull orange and has a wingspread of about 21 mm. The
