HABITS AT NIGHT. 



[Answers to question 23, circular 1, and 30, in Mr. Thomas's additional questions : 

 State all you know about the habits of the young or full-grown insects during the 

 night, and especially whether you have ever known them to march or continue to 

 fly after the sun is down, and if so, how long into the night.] 



IOWA. 



Alia, Buena Vista County. — ^Neither fly nor eat, but sit still where they are when 

 night comes. — [Thompson.] The very young get under clods or anything to keep 

 warm. The older prefer to ascend anything to roost. Do not march nor fly, but de- 

 stroy where they roost. — [Crowell. 



LaTce City, Calhoun Coi*?ii^.—Tbey will gather on trees, fences, weeds, cornstalks, &.C., 

 to roost. Do not eat nor travel at night.— [Jack. 



Pringhar, O^Brien Comity. — Young insects seem not to eat at night, but seek protec- 

 tion from wind by getting under clods and grass. The grown insects eat a little at 

 night. — [Longshore. 



Sioux City, Woodbury County. — The young 'hoppers are generally dormant at night. 

 As evening approaches they will climb upon straw stubble, fences, small trees, or any 

 other substance that is high and dry, and remain there until morning. The old 'hop- 

 pers seem to work about the same, unless in flight. It is generally thought that they 

 do not light at night unless the wind becomes unfavorable. — [Skinner. 



DAKOTA. 



Sayh'ooTc, Clay County. — Appear to sit still behind the sheltery side of anything, to 

 keep warm. Sit still ; don't eat. — [Hall. 



Olivet, Hutchinson County. — They surely fly at night during their passage, as they are 

 seen every fair day during summer on the wing, but do not light at night. — [Jones. 



Sioux Falls, Minnehaha County. — Young 'hoppers will go Ave or six rods to get into 

 straw or high grass for the night. — [Everett. 



Milltown, Armstrong County. — Think they lie still at night. — [Taylor. 



Wahpeton, Richland County. — Neither fly, march, nor eat at night. Congregate in 

 piles two or more inches deep, or on small shrubs and weeds.— [Smith. 



Walhalla, Pembina County. — Locusts neither fly, march, nor eat at night. — [Miss 

 Mayer. 



NEBRASKA. 



Farmers Valley, Hamilton County. — At night and in rainy weather they go to high 

 grass or stalks lor shelter. I had a field of corn in 1874 that was standing and not 

 seriously damaged when night commenced. The next morning it was only cornstalks, 

 leaves and ears having been eaten. — [J. Vosburg. 



Plattsmouth, Cass County. — The young cluster under leaves, clods, roots, &c., not at 

 night, but in rain and cold weather ; do not eat under such circumstances. The grown 

 remain perched on trees, bushes, &c. When on the wing, I am much inclined to 

 think they fly all night.— [Child. 



Sunlight, Cass County. — Grown ones fly up to roost ; young crawl up on stubble, 

 weeds, &c. — [Babbit. 



Steele City, Jefferson County.— They rest during the night on bushes, cornstalks, 

 &c. — [Gantt. 



Arago, Richardson County.— They crawl up to the top of fences, bushes, weeds, and 

 grain.— [Gerdes. 



Grand Island, Hall County. — Toward evening the young 'hoppers climb bushes, poles, 

 sticks, small trees, and on wet and cold days they seek shelter under anything that 

 will hold them.— [Stolley. 



Hooper, Dodge County. — Never move at night unless disturbed.— [Eisley. 



Pleasant Hill, Saline Countij.—Yonug insects quiet at night. The old ones collect on 

 trees and shrubs, sometimes in sufficient numbers to bend the trees.— [Abbott. 



Chapman, Merrick County.— Thej feed mostly on cloudy days, in the evenings and 

 warm nights. They crawl upon all kinds of vegetation of an evening and stay until 

 the hot sun of the next day, then they seek the shade.— [Cox. 



Fremont, Dodge County.— Do not fly but sometimes eat at night. If flying they will 

 light before sunset.— [Blanchard.
