Hew York C. R, Crosby and assistants: Tent caterpillars are quite 
numerous in all parts of Oswego County. They are found in 
Ontario County in most orchards that have not teen sprayed, 
not serious in Orleans County; also observed on roadside trees, 
in Genesee County. 
J. T. M. Forbes (June 2): Tent caterpillars are coming into 
the last stage* This is to be expected early in June, but is in 
direct contrast with the belated development of most other 
insects this season, 
Leland J. TE. Jones (June 10): Owing to unfavorable and cold 
weather last month, the report was not exact; this pest is 
increasing over former years at Bainbridge. Little is to be 
done to control it. 
Pennsylvania S. W. Frost (June 8): The apple tent caterpillar is abundant 
on. neglected apple, plum, and cherry trees in Adams County. 
Delaware C« 0. Houghton (May 17): Caterpillars are now migrating to 
find suitable places for spinning up. Serious injury has been 
done in many cases, tnees being wholly defoliated. 
Wisconsin S, B. Fracker (June 15): This insect is reported in Columbia, 
Grant, and Marathon Counties; and has been pfensonally observed 
in Dane, Rock, and Walworth Counties. 
Minnesota A. G. Ruggles (June 7): The tent caterpillar was very abundant 
in Orchard Gardens. Ordinarily we see very little of this 
insect in Minnesota. In this part of the State the orchards 
have not been well taken care of and the insect seems to be 
on the increase. 
SPRING CANKFRWORM ( Paleacrita vernata Peck) 
New York C. R. Crosby and assistants: This insect is quite generally 
prevalent over the western New York apple growing section. It 
was so serious this year in Genesee County that a spray ring 
has been formed to fight this pest. It is estimated that the 
trees in the infested area are 75 per cent defoliated. 
Wisconsin S, B. Fracker (June 15): The spring cankerworm is less 
injurious than in 1921 and 1922 in southeastern counties, but 
worse from Madison to Spring Green. 
C» L. Fluke (June 22) : The spring cankerworms have appeared 
in the southern part of Wisconsin in great numbers. At this 
date the damage is nearly over. 
Minnesota A. G. Ruggles (June 7): The spring cankerworms seem to be 
as bad this year as ever in many sections of the State,
