[210] REPORT UNITED STATES ENTOMOLOGICAL COMMISSION. 



in this country the wind changes mostly at night, and in case of their flying over at 

 night a change of wind would cause them to alight, and we should find them in the 

 early morning, where there was none the previous evening. — [N. J. Newell, Athol, 

 Lyon County, Iowa. 



Do not think they fly during the night. So far as I have observed, swarms passing 

 over commence alighting about 5 o'clock p. m., and remain during the night. — [H. 

 Brockway, Luverne, Rock County, Minnesota. 



When on green trees and shrubs they feed very considerably during the night, strip- 

 ping trees of their leaves, and also gnawing the bark so as to girdle small tender barked 

 trees, and giving tougher bark a ragged uneven surface as it grows after. I have 

 never known locusts, either large or small, to move nights. They are clumsy, and not 

 inclined to move when the thermometer is below 60°. I do not think the eggs devel- 

 ope at all with the thermometer below 60°, and perhaps 65°. I should like to know 

 at what point of warmth the eggs develop. — [C. C. Perkins, Oswego, Kans. 



Never saw them travel at night. As long as dew or rain lasted they huddled to- 

 gether on tall weeds or plants, grape-vines, small trees, poles, &c.— [Herman Jaeger,
