Seasonal Activity
Adults are most often reported from April to September.
Diet and Behavior
Diet: Larvae feed on developing cones of various species of pine
Life History
In northern states, they overwinter as first-instar larvae in hibernaculae spun beneath bark scales on branches of red pine. In spring, larvae feed on staminate flowers, later they tunnel in 2nd-year cones. ( 3 ) In southwest, winter is spent as a partly-grown larvae in newly formed cones. Pupation occurs in damaged cones. ( 3 ) One generation per year. ( 3 )
About Butterflies and Moths: the wider group
Order-level background for Lepidoptera, the group containing Dioryctria disclusa. 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.
