greenish-white with interrupted longitudinal stripes of dark 
brown. The winter is spent either in the larval or pupal stage 
and there are up to four generations per year in the Deep South. 
The American plum borer, Huzophera semifuneralis (Walker), 
is widespread and attacks a wide variety of hardwoods, includ- 
ing plum, wild cherry, apple, London plane, mountain ash, wal- 
nut, persimmon, mulberry, basswood, poplar, sweetgum, and 
gingko. Serious infestations have occurred on young London 
plane trees in newly developed areas on Long Island. The larvae 
bored in the trunks and larger branches, and were associated 
with a canker condition. 
Euzophera ostricolorella Hulst has been recorded from Long 
Island to South Carolina and westward to Ohio, Kentucky, Ten- 
nessee, and Louisiana. Its preferred host appears to be yellow 
poplar, but it also attacks magnolia. Heaviest infestations on 
yellow poplar are found at the base of trees over 10 inches in 
diameter (325). Attacks above a height of 2 feet on the trunk are 
rare. The larvae feed in the inner bark, excavating tunnels which 
extend both above and below the ground line. Winter is spent 
in the pupal stage in the tunnel. There appears to be one genera- 
tion per year in the North and two per year in the South. Trees 
of all sizes may be killed by heavy infestations. 
Euzophera magnolialis Capps has been observed damaging or 
killing magnolia seedlings in Florida nurseries. The adult has a 
wingspread of about 25 mm., and the forewing is puprlish-brown, 
with black terminal dots. Full-grown larvae are white and flat- 
tened, they taper toward the rear and are about 28 mm. long. 
Attacks occur at the base, the larvae tunneling in the lower inches 
of the trunk and in the larger roots entering the crown. Heavily 
infested trees may be girdled and killed( 134). 
Canarsia ulmiarrosorella (Clem.) occurs in southern Canada 
and throughout eastern United States. The larvae feed on the 
leaves of elm which they web together with silk. The adult has 
a wingspread of 15 to 20 mm. The forewings are dusty white 
and crossed by dark gray or blackish bands. Mature larvae are 
green, sparsely hairy and about 18 mm. long. Winter is spent in 
the pupal stage, and there are two generations per year. This 
species is sometimes abundant enough to attract attention, but is 
seldom injurious. 
Moodna ostrinella Clemens is rather widely distributed in 
southeasten Canada and eastern United States. In Canada, the 
larvae have been found in second-year pine cones damaged by 
other insects. They have also been found in pine cones in Ar- 
kansas; in sumac heads in New York, Pennsylvania, and Texas; 
and in fusiform rust cankers on slash and longleaf pines in Flor- 
ida. Full-grown larvae vary from yellow with a greenish tinge 
to bright yellow orange or orange, and are about 8 to 10 mm. 
long. 
Actrix nyssaecolella Dyar is a leaf folder or leaf roller of 
tupelo from western Pennsylvania to New Jersey and Massachu- 
setts. The adult is powdery gray and has a wingspread of 15 mm. 
Full-grown larvae are black with yellow heads. Winter is spent 
in the pupal stage, and larvae are present during July and 
August.
