Insects of Interest

Weevil belonging to the Polydrussus genusA lot of green beetles have been showing up in a variety of crops; alfalfa, small grains, vegetable gardens, roadsides, all have seen these short snouted weevils. These are commonly called Pale Green Weevils and are species of the Polydrussus genus. They’re associated with tree species (birch, poplar, etc) but feed on a variety of broadleaf plants. They notch leaves and we’ve received a couple of calls of them becoming troublesome in strawberries and garden vegetable crops. Populations build over time (the last time we had loads of these little critters was the late 1990’s) and they may be motivated to leave trees and find greener pastures in gardens because of our dry conditions this summer. These green beetles should disappear soon after the first week or two of July.
