Spring threshing surprise - Seeking beetle data please!

Reminder - Large numbers of adult Amara ground beetles are being reported this spring (Fig. 1) in canola fields left unharvested last fall. These are non-pest beetles.  Adults feed on seeds, particularly those of cruciferous plants.  Larvae eat pest insects (e.g., grasshopper eggs).

carabids observed in central Alberta in the autumn of 2010.  Photo B. Berry.
