Defoliating catepillars attack the trees
A mix of more than three caterpillar species began their decent upon the Sanctuary and many other nearby areas. Frank Snyder with the Bureau of Forestry told us the mix of pests include fall cankerworms, oak sawfly, oak leaf rollers, cankerworms,
sawflies, gypsy moth, and other native defoliators.
He warns to expect the worst in some
portions of the county and probably more wide spread defoliation then we have seen in years. However, cooler weather and/or rain may help.
