The larva lives within the tube it constructs by drawing from 5 to 20 needles 
together and fastening them with silk. It feeds on the tips of these needles (fig. 62). 
Winter is spent in the pupal stage within the tube. There may be two generations per 
year. Heavily infested pines often have a ragged appearance. This may be objec- 
tionable where valuable ornamentals are involved.

The hickory leafroller, A. jug/andana (Fernald), occurs in southern Canada and 
throughout the Eastern States. Its principal host is hickory, but it will feed on plum 
and viburnum. The adult is dark brown and has a wingspread of about 21 mm. The 
front wings are marked by two parallel, oblique, blackish bands. Full-grown larvae 
are pale to translucent, with pale green heads tinged with brown; larvae are about 20 
mm long. They feed from within longitudinally rolled leaves and pupate beneath 
the bark on the trunk of the tree. 
Argyrotaenia quercifoliana (Fitch) occurs in southern Canada and south to 
Florida and Texas. The larvae feed on the foliage of red, black, white, scrub, and 
pin oaks. The adult is cream yellow marked with light-brown dots and has a 
wingspread of about 20 mm. The forewings are marked with two oblique brown 
bands, and the hindwings are white. Full-grown larvae are light green except for 
amber-yellow heads and are about 20 mm long. This species sometimes causes 
serious defoliation locally.
