REPORT OF THE STATE ENTOMOLOGIST I9OO IOOI 



while in some places it appeared that cold and wet actually did kill 

 many of the caterpillars, it was the opinion of most that fatalities were 

 comparatively limited, and several observers demonstrated that the 

 recently hatched caterpillars were very resistant to climatic influences. 



Some of the records may appear trivial, but a life history is nothing 

 more than the sum of many small facts. The value of the records 

 relating to the appearance and relative abundance of the different insects 

 will increase with the length of the period over which they extend. 

 These records will also show in time the effects on insect life of the 

 different climatic conditions in the various sections of the state. 



Summaries of reports from voluntary observers 



The names inserted in brackets indicate determinations made by the 

 entomologist. The others are presumably correct except where ques- 

 tioned. The dates given after the records are those ol the reception of 

 the reports, and they are from one to three days later than the writing 

 of the report. 



Albany county (E. T. Schoonmaker, Cedarhill) — Appletree tent- 

 caterpillar [Clisiocampa americana]. Egg clusters are abun- 

 dant and the prospect is that the caterpillars will be numerous. Ap. 17. 

 They have already formed small nests or webs. May 1. Fiery ground 

 beetles and June bugs are exceptionally numerous in cultivated fields. 

 Appletree tent-caterpillar work is beginning to be apparent. Elm leaf 

 beetles [Galerucella luteola] are to be found in buildings, but 

 they have not attacked the young foliage. May 8. Appletree tent- 

 caterpillars were very active on Wednesday and had suffered no notice- 

 able injury from the hard freezes. They were dormant on cold, cloudy 

 days and on warm days active. There were no signs of injury to either 

 species of tent-caterpillars, though the thermometer stood at 27. June 

 bugs were present in exceptionally large numbers the evening of May 12. 

 May 15. Forest tent-caterpillars [Clisiocampa disstria] are 

 stripping apple, plum and maple trees, though they were not injurious in 

 this locality till the present season. They are gathering in bunches of 

 hundreds on the limbs or spin down on webs. May 28. Potato beetles 

 [Doryphora 10-lineata] have appeared in small numbers. 

 Forest tent-caterpillars are still doing some injury. Rhubarb curculios 

 [Lixus concavus] are injuring rhubarb to some extent in limited 

 sections. June 5. Rose beetles [M aero d a c tylus subspinosus] 

 have appeared and potato beetles are abundant. Forest tent -caterpillars
