REPORT OP THE STATE ENTOMOLOGIST 1901 781 



appletree tent-caterpillars [Clisi'ocampa a m e r i c a n a] 

 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 [Conotrache- 

 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]. May 8. 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- 

 caterpillar [Clisiocampa disstria] was found. Horn 

 flies [Haematobia serrata] are very troublesome to 

 cattle. June 22. 



Genesee county (J. F. Kose, 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 fouud they were scattered for a distance of 2 feet
