GENERAL FEEDERS 
GPASSHOPPERS (Acrididae) 
Wisconsin. E. L. Cham"bers (May 20): Melanoplus mexicanus Sauss. was 
observed hatching in quite large numbers in spots located in light sand 
areas of northern Wisconsin, where there has "been little or no rain 
this spring. 
Iowa. C. J. Drake (May 20): Grasshoppers are extremely abundant in western, 
southwestern, and southern Iowa. They are probably more abundant than 
they have been at any time during the past 20 years. The heaviest in- 
festation is along the Missouri River and in the southwestern corner of 
the State. On Muscatine Island, in the Mississippi River, the hoppers 
have completely wiped out a number of truck patches. Fairly heavy infes- 
tations have been reported at Ottumwa and Waterloo. 
Missouri. L. Haseman (May 23): Grasshopper young appearing in swarms on dry 
ground. Apparently most of them are the common Carolina locust 
( Schistocerca americana Drury) , although we have not closely checked 
nymphs for specific determination. 
North Dakota. F. G. Butcher (May IS): Recent field observations indicate 
that grasshopper infestations correspond closely to earlier forecasts. 
Some eggs are reported hatching in the southern counties. Predators 
have been responsible for the destruction of a small percentage of eggs, 
but otherwise practically all of the eggs are viable. 
Nebraska. 0. S. Bare (May 19): Hatching of eggs is proceeding at a rapid 
rate and the young hoppers are appearing in great numbers along road- 
sides, pasture edges, ditch, cut banks, and sod fence rows. 
M. H. Swenk (May 20): On April 23 an inquiry was received from 
Webster County regarding the control of grasshoppers. 
Oklahoma. C. F. Stiles and F. A. Fenton (May 25): Grasshoppers have been 
reported as very numerous in pastures in northern Oklahoma. They are 
moving to alfalfa and row crops. (May 26): We visited Osage County 
and found four species of grasshoppers very numerous. Alfalfa is being 
severely damaged. M. femur - rubrum DeG. is the predominant species and 
M. diff orentialis Thos. is quite abundant. 
Colorado. G. M. List (May 22): Eggs have hatched well, and if the weather 
is favorable the infestation will be rather heavy for the egg population 
observed last fall* Poisoning is now under way in several counties. 
Utah. C. J. Sorenson (May 20): Grasshoppers have been hatching during the 
past 2 weeks at Kanosh and are very abundant. 
G. F. Knowlton (May 11): Grasshopper nymphs are causing moderate 
damage to dewberries at Orem, in Utah County, and to wheat near Lehi. 
Second- and third-instar nymphs are moderately abundant on the
