MOEMON CRICKET ( Anabrus sinplex Hald.)_ 
General* C. Wakeland (June IS): No infestations have developed in the Big 
Horn National Forest of Sheridan County, Wyo, , from very heavy depositions 
of eggs in higher elevations, and it appears that there will he few 
crickets migrating from there to crop areas. The large hands of crickets 
in Bi^’Horn and Yellowstone Counties, Mont,, are in higher elevations 
remote from crop areas, where succulent vegetation is so abundant that 
little injury is apparent, and no extensive migration to crop areas is 
expected. Crickets now largely in the adult stage, and, if they react 
as in previous years, their tendency will he to migrate higher rather than 
toward crops. Some migration reported as taking place in western Idaho 
from higher elevations to the crop lands, hut crop protection has heen so 
effective that it is expected that injury will he prevented, even if 
migration takes place. Reports from eastern Idaho indicate that control 
has heen very successful. 
South Dakota, (June 9-15)5 Infestation in the Rosebud area, in Jones and 
Lyman Counties, and in northv;estern and central Mellette and Lyman 
Counties and in western Jones County reported as heavy. In some of the 
areas crickets were fovind at the rate of from 50 to 100 per spuare yard. 
Bands have heen found which are from 1 to 1-g miles wide and 5 miles long, 
Montana, (June 9"15)5 Only a few migrations reported. In most sections the 
crickets r?=nge from third instar to adult stage. In the Sanders County 
area eggs are still in the early stage of development, yet crickets are 
in the adult stage and some mating has taken place, 
Wyoming, (June 9**i5)5 A small amount of crop damage, confined largely to 
grain, has heen noticed, hut it appears that damage will he comparatively 
light. Crickets are in the adult stage at the lower elevations in Hot 
Springs County, whereas on the higher slopes of the Owl Creek Range 
they are largely in the sixth and seventh instars. In the Big Horn 
Mountains of Sheridan County there are still numerous unhatched eggs. 
In Crook County crickets range from the third to the sixth instars, with 
unhatched eggs present at the higher elevations, 
Nevada, (June 9*~15)5 Rather serious migrations into crop areas have 
occurred at South Fork, and minor damage has heen done to cultivated 
crops. Movements of crickets are rather general throughout the infested 
areas in the State, The greater number of the crickets are now adult, 
and copulation was noted on June 13 in areas south of Elkoi On June 15 
crickets were practically continuous for 3^ miles south of Elko, 
Idaho, (J\ine 2-S)i Mormon crickets throughout the infested eastern part of 
the State are mostly in the adult stage at the lower elevations, while 
in the higher regions they are in third to fifth instars. Gravid females 
were reported on June 8 in Madison County.
