Spruce Budworm Moths are not common in Maryland. They are a species mainly of the northern coniferous forests of Canada and the northern United States. Their range coincides with spruce and fir trees.


The caterpillars of the Spruce Budworm Moth are an important food source for the young of northern finches, such as Evening Grosbeaks, Purple Finches, and Pine Siskins. Years in which Spruce Budworm Moths are abundant result in large populations of northern finches, which, if they exhaust their northern conifer-seed food sources in the autumn, may migrate south in search of food. During these "irruption" years, northern finches often reach Maryland.

There are 13 records in the project database.
