K. Johnson, 1976

Cedar Hairstreak

Callophrys gryneus plicataria is a of juniper hairstreak in the Lycaenidae. It is treated as a synonym of Mitoura gryneus in some taxonomic systems, reflecting ongoing debate about generic placement within the Eumaeini. The subspecies is associated with cedar and juniper . Observations are concentrated in the northeastern United States, particularly Vermont.

Identification

Distinguished from other Callophrys/Mitoura by combination of plant association (cedar/juniper), geographic range (northeastern US), and subtle wing pattern differences. Differs from nominate C. gryneus gryneus in details of underside pattern and genitalia. Separation from C. hesseli (Hessel's ) requires careful examination of wing pattern and genital dissection; C. hesseli typically shows more prominent white W-shaped postmedian line on hindwing underside.

Appearance

Small with olive-green to brownish upper wing surfaces. Underside of hindwing typically shows fine white postmedian line with distinctive pattern of dark and light scaling. with white-ringed clubs. Wing margins often slightly notched or tailed on hindwing. Overall coloration provides cryptic camouflage when perched on plant foliage.

Habitat

Associated with eastern red cedar (Juniperus virginiana) and other juniper . Occupies open woodlands, forest edges, cedar barrens, and areas with scattered cedar trees. often remain close to plants.

Distribution

Northeastern United States; documented from Vermont and surrounding region. Distribution centered on areas supporting native Juniperus virginiana.

Seasonality

active in spring, with period typically April through June depending on latitude and weather conditions. Single-brooded.

Host Associations

  • Juniperus virginiana - larval plantEastern red cedar
  • Juniperus - larval plantJuniper generally

Behavior

often perch on plant foliage with wings closed, showing cryptic underside. Males patrol territories around host trees. Adults may visit flowers for nectar, including milkweeds (Asclepias spp.) and other spring-blooming plants.

Ecological Role

of spring wildflowers. Larval herbivore on native junipers. Prey for birds, spiders, and predatory insects.

Human Relevance

Subject of interest for watchers and naturalists. Conservation concern in some areas due to loss and fragmentation of cedar barren .
