Excerpt from Cooperative Economic Insect Report, Vol. 14: April 17, 1964 Fall webworm was very heavy in central and western areas of Pennsylvania, and defoliation was more prevalent than in any previous year throughout southern Indiana. Fall webworm nests were very abundant in the Mesilla and Pecos Valleys of New Mexico by mid-june and heavy infestations again appeared on various hosts in September and October in the State. Spring cankerworm and fall cankerworm were damaging and of concern in several areas from New England to California. Several species of tent caterpillars were of concern during 1963, with damage ranging up to severe defoliation in some areas, especially on oaks in central Texas.
