Summary

Did you know?

As with other hairstreaks, the tails and eyespots on the hind wings resemble a head. Movement of the tails is believed to attract a predator's attention away from the vital areas.

State Ranking Justification

This species could be undergoing a slight range expansion in New York. It is sometimes found at relatively high abundance and it has been found at numerous locales along coastal New York. Because it appears to be a generalist, occupying heavily urbanized areas and feeding on a variety of common food sources in both the adult and caterpillar stage, threats to the viability of populations are unclear at this time. It is likely that this species will be removed from the active tracking list in the future.

Short-term Trends

Glassberg (1993) and Cech and Tudor (2005) stated that this species was expanding northward, and although it is sometimes reported in modest numbers around New York City (Fiore and Wallstrom 2003-2006), there does not appear to be a sustained ongoing range expansion farther north in New York in recent years and the current range is similar to that shown in Shapiro (1974).

Long-term Trends

This species extended its range northward and colonized metropolitan New York City sometime after 1950 and became locally common in lowland areas (Shaprio and Shapiro 1973).

Conservation and Management

Threats

Because this species seems to be expanding in New York, threats are unclear. In general, urbanization, habitat loss and insecticide spraying can threaten butterfly populations in metropolitan New York City (Matteson and Roberts 2010).

Conservation Strategies and Management Practices

In general, management strategies for ruderal insects of heavily urbanized areas are not relevant (NatureServe 2009). Nevertheless, Matteson and Roberts (2010) suggested three conservation strategies for butterflies of metropolitan New York: 1) locate and promote conservation of early-successional habitats such as pine-oak barrens, wet meadows and serpentine and calcareous grasslands; 2) assess the status of host plants; and 3) population monitoring.

Research Needs

Very little is known of the biology and life history of this hairstreak, especially in the northern part of its range. Potential mechanisms of range expansion and population dynamics have not been addressed. Caterpillar detritus feeding is unique and deserves further study (Cech and Tudor 2005).

Habitat

Habitat

On Long Island these butterflies are primarily found in and around scrub oak forest and edges, but also in hammocks, fields, right of ways, brushland, and occasionally yards with foodplants. Adults are seen mostly in the open and on edges of scrub oak forest but can be encountered in shadier situations in hotter weather. Adults commonly visit gardens (NatureServe 2009). This hairstreak is most common in successional old fields with thick vegetation and in hammocks behind coastal dunes (Opler and Krizek 1984).

Associated Ecological Communities

  • Coastal oak-heath forest (guide)
    A low diversity, large patch to matrix, hardwood forest that typically occurs on dry, well-drained, sandy soils of glacial outwash plains or moraines of the Atlantic Coastal Plain. The forest is usually codominated by two or more species of scarlet oak, white oak, and black oak.
  • Coastal oak-hickory forest (guide)
    A hardwood forest with oaks and hickories codominant that occurs in dry, well-drained, loamy sand of knolls, upper slopes, or south-facing slopes of glacial moraines of the Atlantic Coastal Plain.
  • Coastal oak-laurel forest (guide)
    A large patch low diversity hardwood forest with broadleaf canopy and evergreen subcanopy that typically occurs on dry, well-drained, sandy and gravelly soils of morainal hills of the Atlantic Coastal Plain. The dominant tree is typically scarlet oak. The shrub layer is well-developed typically with a tall, often nearly continuous cover of the evergreen heath, mountain laurel.
  • Mowed lawn
    Residential, recreational, or commercial land, or unpaved airport runways in which the groundcover is dominated by clipped grasses and there is less than 30% cover of trees. Ornamental and/or native shrubs may be present, usually with less than 50% cover. The groundcover is maintained by mowing and broadleaf herbicide application.
  • Pitch pine-oak forest (guide)
    A mixed forest that typically occurs on well-drained, sandy soils of glacial outwash plains or moraines; it also occurs on thin, rocky soils of ridgetops. The dominant trees are pitch pine mixed with one or more of the following oaks: scarlet oak, white oak, red oak, or black oak.

Range

New York State Distribution

This species is primarily found along the coast from Staten Island east to central Suffolk County, rarely inland to Rockland and Westchester Counties. This forms the extreme northeastern range extent of this northern representative of a tropical group of hairstreaks.

Global Distribution

Kansas and Texas east to Long Island and south to Florida. It is most common on the southeastern coastal plain.

Best Places to See

  • Central Park (New York County)
  • Edgewood Oak Brush Plains Preserve (Suffolk County)
  • Van Corlandt Park

Identification Comments

Identifying Characteristics

The undersurface of the wings is gray-brown with a postmedial white line edged with a bright orange to red-orange band. Each hind wing has two tails (hairstreaks) with a relatively large conspicuous eyespot on the wing margin between the bases of the tails and the wingspan of the adult is about 1.0". Caterpillars are brown with a median dorsal longitudinal stripe and are covered with short hairs (Hall and Butler 2010).

Characters Most Useful for Identification

This species' small size, ventral red postmedian band, dark grayish wings with a dorsal iridescent blue color in flight is diagnostic.

Best Life Stage for Proper Identification

Adult.

Behavior

Males perch on shrubs and small trees watching for females. Females lay eggs singly on the underside of fallen leaves near the host plant. Caterpillars feed on leaves and buds and detritus (Cech and Tudor 2005). Chrysalids and fourth-stage caterpillars hibernate. Newly emerged individuals occasionally sip moisture from puddles on trails (Opler and Krizek 1984).

Diet

Caterpillar hosts: fallen leaves of wax myrtle (Myrica cerifera), dwarf sumac (Rhus copallina), staghorn sumac (R. typhina), and several oaks. Primarily associated with R. copallina on Long Island. Adult food: flower nectar from yarrow, wild cherry, tickseed, sunflower, sumac, sweet pepperbush, New Jersey tea, common milkweed, and dogbane (Opler and Krizek 1984).

Best Time to See

Shapiro (1974) reported the species to be double brooded on Staten Island, with a flight season from July through October while Glassberg (1993) provided data from the New York City area on two flight periods: early May to late June and late July through October. Sightings from Fiore and Wallstrom (2003-2006) are also in line with Glassberg's flight seasons. Individuals remain active throughout the day, but late afternoon is the period of greatest activity (Cech and Tudor 2005).

    Several other Hairstreaks are superficially similar, but none have a red band entirely across the wings.
