Station VII. 2. Beaver Meadow along Little Carp River. Species taken: 

 Camnula pellucida. 



Habitats represented and characteristic species. 



1. Grassy places moist. The species of locust taken here is not 

 characteristic of such conditions, but it is a very common and 

 widely distributed species in the boreal zones, and may occur 

 almost anywhere, especially in grassy places. Its preferred 

 haunts are on dry. upland soils.
