Moths of Concern to Tree Health in High Park

Moths of Concern to Tree Health in High Park

Caterpillars of the introduced Gypsy Moths and native Fall Cankerworm Moths can be heavy defoliaters of trees such as High Park's black oaks. Populations vary from year to year. The Forest Health Care unit of Toronto Forestry monitors these species and takes action to control them as considered appropriate. Oaks are the host plant for a variety of butterflies and moths. The caterpillars that feed on oaks also provide a valuable food source for migrant and breeding songbirds.
