REPORT OF THE STATE ENTOMOLOGIST I9OO IO25 



on apple, plum, peach, cherry, wild cherry, apricot, pear, elder, dogwood 

 and American elm. Some are about two weeks old and J inch long 

 and others are just hatching. May 11. I found 10 soldier bugs [P o di- 

 sus spinosusj around one nest of the tent-caterpillar, one of which 

 was feeding on a caterpillar. I have repeatedly found these bugs 

 with the larva of a potato beetle on the extended beak. May 14. I 

 am now convinced that the recent cold did the appletree tent- 

 caterpillar little harm, for, though some recently discovered cater- 

 pillars were not more than J inch long and had almost no 

 web to cover them, they went through a frost that froze the 

 leaves stiff night before last without the least appearance of 

 injury. May 14. Many of the appletree tent-caterpillars are nearly 

 full-grown and they are more active than ever. The damage to many 

 orchards is something awful, as they have lately been working on a large 

 variety of trees, though they show a decided preference for apple and 

 cherry. In addition to the preceding list, I have also found them work- 

 ing on the thorn (Pauls new double), beech and poplar. May 28. The 

 cankerworm has appeared in great numbers in both orchards and forests. 

 Many orchards are as brown as though burned by fire. Both species of 

 tent-caterpillars have done great damage. June 5. The inclosed beetle 

 [Systena taeniataj has destroyed nearly 20,000 apple seedlings 

 within a week. It was easily controlled by spraying with paris green. 

 The seedlings are cultivated every week, and it was between two culti- 

 vations that the mischief was done. June 27. 



Westchester county (Mrs E. H. Mairs, Irvington) — The cold 

 weather delayed the appearance of the appletree tent-caterpillar 

 [Clisiocampa americana], but did not destroy many. Potato 

 beetles [Doryphora 10-lineata] are unusually numerous, cut- 

 ting young plants off above the surface and devouring eggplants as soon 

 as set out. May 25. 



Wyoming county (W. H. Roeper, Wyoming) — Apple aphis 

 [Aphis mali] is very abundant on the buds. The appletree tent- 

 caterpillar [Clisiocampa americana] made its first appearance 

 today. The insect will probably be very abundant. Ap. 27. The cold 

 weather has kept the tent-caterpillars back, and they are working rather 

 slowly, but the hard frosts do not seem to have killed them. May 12. 

 The warm weather has resulted in much greater depredations by the 

 appletree tent-caterpillars, and in some places they are stripping the 

 trees. May 19. Tent-caterpillars have done very much damage in both
