Tent Caterpillars
Two species of tent caterpillars are important tree pests in New York State. About every decade they become numerous enough in local outbreaks to cause concern. At times the epidemics reach statewide proportions. The buildup of natural control factors eventually reduces tent caterpillar populations to a low ebb, but in the meantime serious defoliation of many kinds of deciduous trees can occur.
