Banded Hairstreak (Satyrium calanus) lives in open woodland across Eastern North America. It feeds on oak tree leaves.
Fascinating facts about the Banded Hairstreak
- The banded hairstreak belongs to the Lycaenidae family of butterflies and is a common hairstreak found east of the Rocky Mountains in North America. As a territorial insect, it actively patrols a defined patch and will confront any other butterfly that drifts into its area, defending its space from intruders.
- Female banded hairstreaks lay each egg alone on a suitable host plant rather than in clusters. The eggs are deposited on oak, hickory or walnut leaves and remain dormant until they hatch in the spring, timing the larvae's appearance with fresh foliage.
- The banded hairstreak produces only one generation each year, with adults emerging in a single brood that flies from early June through late August. This brief flight window encompasses the entire reproductive period, during which mating, egg-laying and larval development are all compressed into a few months. Consequently, the species' whole seasonal activity is confined to the warm summer months, after which the cycle pauses until the next spring.
- The banded hairstreak's larvae feed on the leaves of several hardwood trees, including oak, hickory, and especially butternut walnut. After the eggs hatch in spring, the newly emerged caterpillars begin feeding on the fresh leaves of these trees, gaining the nutrients needed to grow before pupation.
