Eastern tent caterpillar time

While setting up blueberry maggot monitoring traps 2 weeks ago, a grower pulled me aside to look at what he was concerned could become a plague of caterpillars.

Eastern tent caterpillars had taken up residence in one of his pump houses.  These insects are not necessarily pests of blueberries, although they can feed on Vaccinium.  They are more commonly found in trees creating their characteristic tents.  I do not anticipate eastern tent caterpillars posing problems in blueberries, but if they do, we have tools to deal with them.
