It looks like there will be another big outbreak of forest tent caterpillars this summer. The caterpillars are capable of chewing all the leaves from the tops of mature trees.
The population of forest tent caterpillars runs in cycles, but they're not to be confused with eastern tent caterpillars whose sticky tents are easily visible in the branches of smaller trees such as wild cherry and apple.
