Gagne Biology Notes 2
In central Md, galls were first noticed on May 23 when still only bubble-like and containing first instars. Galls were greenish white to light green, somewhat sticky, and covered with close, long white hairs. In subsequent days these hairs became farther apart as the gall quickly elongated along the leaf axis and became darker green. Larvae developed quickly and began to leave the galls by June 9 through the newly opened exit aperture on the upper side of the leaf. Mature larvae are white and active.
