Insect Quiz April, 2006

April Quiz 2006

Now that spring is in the air, you can’t wait to get back out into your yard and garden.  You recall last year in late April and early May seeing an insect problem in your crab apple tree.  Or at least you think it was an insect.  There was a silken web in the fork of two of the branches.  There seemed to be a bunch of ‘worms’ that would feed on the leaves during the day but would return to this ‘nest’ at night.  You were concerned about the leaves being eaten and their presence of this web.
