Habitat and Range

Habitat

coniferous and mixed forests; adults are nocturnal and come to light

Geographic Range

Nova Scotia to Alaska, south in the east to New York, and south in the west to California and New Mexico

Seasonal Activity

adults fly from June to August

Diet and Behavior

Diet: larvae feed primarily on cones (and sometimes shoots and needles) of spruce ( Picea spp.); secondary hosts include Douglas-fir ( Pseudotsuga menziesii ), hemlock, fir, and Lodgepole Pine ( Pinus contorta )

Life History

One generation per year; eggs are laid on hostplant in late summer and hatch before winter; overwinters as a first-instar larva without feeding; larvae feed during following spring, and pupate in late June and early July The eggs hatch in about 10 days and the young larvae, without feeding, spin hibernaculae where they spend the winter.

About Butterflies and Moths: the wider group

Order-level background for Lepidoptera, the group containing Dioryctria reniculelloides. Species-specific details appear above.

Group overview

Lepidoptera includes approximately 180,000 described species of butterflies and moths. Moths outnumber butterflies roughly 10:1. The monarch butterfly's eastern population has declined by more than 80% since the mid-1990s, and the western population by over 95% since the 1980s. The IUCN lists the migratory monarch as Vulnerable.

Ecological role of the group

Butterflies and moths are essential indicators of ecosystem health. As caterpillars, they are a primary food source for birds - a single nest of blue tit chicks requires ~10,000 caterpillars. Adult moths pollinate many night-blooming plants.

Economic and practical significance of the group

Lepidoptera are critical pollinators. In Europe, grassland butterfly species have declined by almost 50% since the early 1990s. In the UK, three-quarters of butterflies are in decline. In the U.S., five butterfly species have gone extinct since 1950, with 29 listed as endangered.
