Wisconsin A. A. Granovsky (August 26): The northern part of Door County is 
seriously infested with grasshoppers , the principal species being 
Camnula n el lucid a. although other species are present. The loss 
in crops is from slight to almost complete. The grains, such as 
barley, oats, wheat, and even rye, suffered badly. Clovers and 
alfalfa were defoliated at Sturgeon Bay, reducing the value of hay,

being found in seme specimens.
