REPORT OF THE STATE ENTOMOLOGIST 1901 781 
appletree tent-caterpillars [Clisiocampa americana] 
are seen on wild cherry. July 2. The work of the Hessian fly 
is becoming more apparent as harvest time approaches, and 
nearly every stem of wheat is infested. I have an idea that the 
wheat will yield better than some people surmise at present. 
I have just been examining my asparagus and have been unable 
to find any beetles or slugs. Plum curculios [Conotrac he- 
lus nenuphar] seem to be worse than usual this year. 
White grubs or something of that nature must be working in 
my sheep pasture, as much of the grass is pulled up by the sheep. 
It seems to be cut off below the surface of the ground by some 
insect. July 16. Grasshoppers are now very numerous, and my 
crop of celery for home use has been destroyed by them. 
July 20. : 
Fulton county (Cyrus Crosby, Cranberry Creek)—Appletree 
tent-caterpillars [Clisiocampa americana] do not ap- 
pear to be very abundant, as I have seen but one nest on an 
appletree so far this year. Appletrees in this vicinity are nearly 
all badly infested with the appletree bark louse [Mytilaspis 
pomorum|]. May8. The cold damp weather has checked the 
development of insects very much. The nests of the appletree 
tent-caterpillars are beginning to show up, but they are by no 
means as thick as they were in Yates county last year. May 17. 
I find little beetles [Typophorus canellus, a strawberry 
root worm] on elms. They were very common two weeks ago. 
June 6. There are a few appletree tent-caterpillars near May- 
field, but elsewhere I have seen none. Only one forest tent- 
eaterpillar [Clisiocampa disstria] was found. Horn 
flies [Haematobia serrata] are very troublesome to 
cattle. June 22. 
Genesee county (J. F. Rose, South Byron)—Appletree tent- 
caterpillars’ eggs [Clisiocampa americana] began 
hatching about Ap. 25, and they are now very numerous. One 
cold day I climbed into a tree for the purpose of crushing the 
‘caterpillars in a nest. It was an ideal day for them to be at 
home, but I found they were scattered for a distance of 2 feet
