FOEEST AND SHADE-TREE INSECTS 
BAGWORM ( Thyridopteryx ephemerae f orri s Haw.) 
New Jersey. R. B. Lott (August 17): Entire defoliation of quite large yellow 
locust trees near Freehold. 
Pennsylvania. C. A. Thomas (August 24): Bagworms caused considerable injury 
during July to arborvitae, blue spruce, Norway and Japanese maples, and other 
trees and shrubs in southeastern Pennsylvania. (August l): Bagwoms are 
now migrating to other trees, presumably for pupation. 
Indiana. H. 0. Deay (August 26): Bagworms were received from Sullivan, August 
19, where they were seriously injuring ornamental plantings of blue spruce. 
Minnesota. A. G. RuggLes (August 23): Bagworms are more abundant than usual this 
year on arborvitae. The past few years the weather has been. very mild during 
the winter months and infestation by this insect is building up. I believe 
the insect would not stand an old-fashioned Minnesota winter. 
Nebraska. M. H. Swenk (July 20 to August 25): A report of damage to evergreen by 
the bagworm was received from Richardson County the second week in August. 
Mississippi. C. Lyle (August 23): Heavy infestations on arborvitae have been 
reported recently from Amory, Vicksburg, and Pine Valley. 
GIPSY MOTH ( Porthetria dispar L.) 
Pennsylvania. Office of Information, Press Service, U.S.D.A. (August 8): The 
gipsy moth was discovered late in July in northeastern Pennsylvania near 
Pittston in Luzerhe County. This insect was found in an outlying district 
back in the mountains, .consisting principally of cut-over land. Information 
at hand indicates that an area about 8 miles long and 4 miles wide has al- 
ready been found to be involved. The chances are that when the survey is 
completed it will be found that a considerably larger area is infested. 
The extent of the infestation indicates that the gipsy moth has been present 
in this region for a period of possibly 15 years. 
FALL WEBWORM ( Hyphantria cunea Drury) 
Maine. H. B. Peirson (August 12): Pall webworms are very prevalent' on elm and 
willow in the vicinity of Augusta and Georgetown. 
Connecticut. ¥. E. Britton (August 23): Apparently this insect is less abundant 
than in 1931. Attacking shade, fruit, and forest trees. 
Pennsylvania. C. A. Thomas (August 24): Fall webworms are now abundant on wild 
cherry, apple, hickory, walnut, and a number of other tree species, and have 
entirely defoliated some walnuts and cherries. 
Delaware. L. A. Stearns (August 23): The fall webworm is noticeably abundant in 
northern Delaware — less abundant, however, than at this date last year. 
Virginia. C. R, *<7tfilley (August): Fall webworms arc very abundant in forests of 
swampy sections from Richmond to Newport News and from Petersburg to Suffolk 
and Norfolk.
