F03EST AND SHADE-TREE INSECTS 
SATIN MOTH ( Stilpnotia salicis L. ) 
New Hampshire .and Vermont. J. V. Shaffner, Jr. (July IS): A few large Carolina 
poplar trees at White River Junction, oastern Vermont, infested. When 
examined on July lU, many larvae had died from wilt disease, hut a 
sufficient number had completed development to produce a heavy deposit of 
og^s. A row of poplars across the river in West Lehanon, N. II., is also 
heavily infested, 
Connecticut. S. S. Crossman (July ll): Large numhers of adults reported as 
gathered around electric lights in Torrington, Litchfield County, during 
the week ending ^n June 25. Eirst record of flight this year. 
EOEEST TENT CATERPILLAR (Malacosoma disstria Hbn. ) 
New Hampshire. J. 0. Conklin (July 26): While ahun&ant in a few localities in 
the State, it is much less numerous than in 1937* 
Vermont. J. V. Schaffner, Jr. (July): Many thousands of .acres of sugar maple 
orchards and fororts in Vermont are heavily infested, hut the defoliation 
did not roach the complete stripping point except in a few small areas. 
Most of the larger infestations prooahly average 75 percent defoliated. 
Ohservations indicate that, in general, the infestations in Addison, 
Rutland, and Dennington Counties, western V e rmont, are on the decline, 
hut defoliation is more apparent in some sections of Windsor and Orange 
Counties, cast-central Vermont, than in 1937* Many sugar orchards show 
the effects of the severe defoliations of the past 1 to U years, and in 
some localities many dead and dying trees have "been cut. 
Massachusetts. A. I. Bourne (July 23): Adults flying in largo numhers during 
•the first 10 days of July, particularly in the northern part of the 
Connecticut Valley. Swarms of moths caused considerahle annoyance along 
the Mohawk Trail, particularly in Shelhurne and Shclhurnc Falls. 
New York. J. V. Schaffner, Jr. (July): Infestations i-re severe, particularly in 
Sullivan, Delaware, and Broome Counties, southern New York. 
Ohio. E. W. Mendenhall (July 19): Pound on elms at Columhus. 
WESTERN TENT CATERPILLAR ( Malacosoma pluvialis Dyar) 
Washington. W. W. B^kcr (July 7): Larvae were causing serious damage i n a logan- 
"berry field, an unusual occurrence. This species occurs on Vaehon Island, 
in Takoma and the Puget Sound areas, and is present in extremely large 
nunhors each year, though not so ahundant this year. Another species of 
Malacosoma was present in small numhers.
