oe and are about 18 mm. long. Larvae are present from May 
to July. 
The European pine shoot moth, Rhyacionia buolinana (Schiff.) 
(fig. 142), an introduced species first recorded in North Amer- 
ica on Long Island, N.Y., in 1914 (127), is now widely dis- 
tributed in the Northeastern States and southern Canada. Out- 
lying infestations also occur in Washington, Oregon, and British 
Columbia. Its hosts include Scotch, red, Austrian, mugho, Japa- 
nese red, Japanese black, ponderosa, eastern white, jack, pitch, 
longleaf, and Virginia pines (527). Red, mugho, Scotch and Aus- 
trian pines are most heavily attacked in eastern United States, 
especially red and mugho. The adult moth is rusty orange-red 
and has a wingspread of about 18 mm. The forewings are marked 
with several irregular, forked, silvery cross lines; the hindwings 
are plain dark brown, and the legs are whitish. 
Adults appear in late spring and fly at night. They lay eggs 
singly or in groups of two to ten on the bases of buds, on needle 
fascicles and twig tips, or on the bark of new and old shoots.
