Insects of Interest
A
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.
