REPORT OF THE STATE ENTOMOLOGIST I9OO IOII 



occurred the preceding two years, but they have invaded new territory, 

 and it is doubtful whether their numbers have been reduced. June 21. 

 [Birch twigs with the petioles occupied by a small curculionid larva were 

 received with the following statement from Mr Flint.] The effects 

 are very noticeable in the vicinity of Pinehill, Ulster co. and adjacent 

 territory. The leaves are mostly wilted and some of them have turned 

 brown. June 30. Cherry aphis [Myzus cerasij is numerous in some 

 parts of Athens. July 3. The elm leaf beetle is doing considerable 

 damage in the river section of this county, but it is not so serious as last 

 year. It does not appear to be present any great distance from the river. 

 Aug. 3. A second brood of elm leaf beetles is now developing. The 

 injury to maples in certain parts of this county is irremediable, as in the 

 towns of Jewett, Lexington, and also in Worcester and Decatur, Otsego 

 co. The fall web worm [Hyphantria cunea] is present in rather 

 small numbers. Aug. 26. 



Herkimer county (G. S. Graves, Newport) — More than 90% of 

 the egg belts of the forest tent-caterpillar [Clisiocampa disstria] 

 are on the maple trees. Many of the egg belts are quite irregular in 

 form. Oct. 16. There do not appear to be more than 25% as many 

 egg belts as there were last fall. Ap. 5. Brown and black woolly bears 

 [Pyrrharctia isabellaj are very abundant, even crawling on the 

 snow. The pupils in school 21 of Utica collected 11,729 egg clusters of 

 the forest tent-caterpillar this spring. Ap. 17. Appletree tent-caterpillars 

 [Clisiocampa americana] were first noticed last Sunday, the 

 2 2d, and since that time they have appeared in considerable numbers, 

 particularly on appletrees. Forest tent-caterpillar eggs are practically 

 free from the protective covering. Ap. 28. Both species of tent-cater- 

 pillars are hatching rapidly and in numbers, the forest tent-caterpillars 

 appearing four days later than the others. May 4. All the forest tent- 

 caterpillars seen by me on the 5th and 7th seemed to be alive, and on 

 the latter date they were warmed up enough to drop readily 

 on threads when the limbs were jarred. The recent cold does not 

 appear to have affected them. May 10. I examined today 500 to 

 1000 clusters of caterpillars of both species and feel justified in saying 

 that they were not harmed by the cold weather. I saw in several in- 

 stances the cast skins of caterpillars, and at first could not locate their 

 present whereabouts, but in each case they were finally found. No cat- 

 erpillars have as yet been seen on the maples, which are leafing out very 

 slowly. May 14. Case-bearers [probably the cigar case-bearer, C o le - 

 ophora f 1 etcher ell a] are quite numerous on the apple. May 19.
