NatureServe Status

Global Status: G3G4
Global Status Last Reviewed: 30Mar2008
Global Status Last Changed: 01Sep1998
Rounded Global Status: G3 - Vulnerable
Reasons: Uncommon to rare and found in small very localized colonies. Some documented losses. Clearly not nearly as widepread and common as the foodplant and often absent in seemingly suitable habitat. Need more information on true status, especially what percentage of SYMPLOCOS sites have colonies and why it is absent at so many. Seems most likely to be globally uncommon to rare (G3), especially if common fire practices do pose a threat to populations, but could be widely overlooked. Not imminently imperiled nor demonstrably secure.

Ecology & Life History

Basic Description: A hairstreak butterfly.
General Description: A single brooded hairstreak most similar to S. LIPAROPS and S. calanus falacer..
Diagnostic Characteristics: 30-36 mm. On a spread specimen the postmedian line on the forewing is distinctive in that the anterior third is strongly angled inward. This probably will not show in the field. Two characters that are probably reliable are the indentation on the hindwing just above the tail spots at least on males, and the orange cap inwardly on the blue tail spot. The bands are not fragmented as on S. liparops. Persons not familiar with this species should consult the descriptions and illustrations in Opler and Malikul (1992) and either Glassberg (1999) or Glassberg et al. (2000). A specimen or two, preferably a male, is very strongly advised for vouchering any new occurrences since a photograph may fail to show diagnostic characters clearly.

Non-Migrant: N
Locally Migrant: N
Long Distance Migrant: N
Mobility and Migration Comments: Local and sedentary but must occasionally disperse some.
Palustrine Habitat(s): FORESTED WETLAND
Terrestrial Habitat(s): Forest - Hardwood, Forest - Mixed, Woodland - Conifer, Woodland - Hardwood, Woodland - Mixed
Habitat Comments: Mesic ravine forests, other mesic to swampy woodland or forest with adults occurring mostly close to the sweetleaf bushes. Lack of fire may very well be a critical habitat feature. Unlikely to be found in places subject to fires sufficient to burn over entire stands of sweetleaf. There could be other habitat needs as this species is nowhere near as common as the foodplant overall.
Adult Food Habits: Nectarivore
Immature Food Habits: Herbivore
Food Comments: Despite old reports of others, sweetleaf (SYMPLOCOS TINCTORIA) appears to be the only larval foodplant.
Adult Phenology: Diurnal
Immature Phenology: Hibernates/aestivates
Phenology Comments: Most of the year is spent as eggs probably on the hostplant bushes. Larvae feed on new foliage and possibly other parts in the spring. Pupal stage is brief (probably about three weeks), almost certainly in the litter. Adults occur somewhat later than most single brooded hairstreaks, varying with latitude etc. from about May to July.

Management Summary
Help
Stewardship Overview: Likely management issues include prescribed burning and Gypsy Moth related impacts. How sensitive larvae would be to BTK cannot really be predicted, unless exposure would be as first or second instars. We do not know if Gypsy Moth larvae eat the foodplant or if defoliation might occur before S. kingi larvae complete feeding. The short-term effect of fire is somewhat easier. There is little chance of significant survival of eggs on or at the base of sweetleaf bushes during a fire, and in the case of winter or spring fires food probably would not be accessible to hatchlings if a few eggs did survive, except in skips. However the longer-term effects of fire need investigation. Most collections have apparently been in or near unburned forest. The absence of this species at most stands of the foodplant cannot now be explained. However there has to be concern about possible habitat fragmentation and prescribed burning.

Biological Research Needs: Need better knowledge of population status and habitat needs
Population/Occurrence Delineation
Help
Group Name: Forest and Woodland Hairstreaks

Use Class: Not applicable
Minimum Criteria for an Occurrence: A location where the species occurs, or has occurred, where there is potential for persistence or regular recurrence. Minimally, a suitable habitat (generally woodland or forest) with the larval foodplant where the species as been verified based on specimens or positively identified photographs for most species. For a number of taxa, not all individuals can be positively identifed from photographs. Due to the frequency of misidentifications in the literature and lack of completely reliable wing characters, genitalia examination would generally be the minimum verification for S. CARYAEVORUM. EOs may include nearby nectar sites when these are adjacent to but different than breedin areas.
Mapping Guidance: EO should be mapped to include all contiguous or nearly contiguous habitat subject to IE.
If the species is associated with a discrete natural community occurrence do not create more than one EO within that community unless the foodplant is absent over gaps of at least half the suitable habitat distance and consider whether the community boundaries should also be used for the EO boundaries. Consult the habitat and food comments fields for species-specific information on what constitutes suitable habitat when mapping occurrences.

Separation Barriers: None known.
Separation Distance for Unsuitable Habitat: 2 km
Separation Distance for Suitable Habitat: 10 km
Alternate Separation Procedure: On islands it may be reasonable to consider all colonies as one metapopulation even if these distances are exceeded somewhat.
Separation Justification: These butterflies are rarelyseen more than at most a few hundred meters out of habitat and generally leave it only in search of nectar. On the other hand habitats are usually large (very often >>1000 hectares) for many of the species and in such cases most species seem to occur widely throughout the habitat. Some species are very dispersive, probably especially the subtropical ones that barely enter the USA. There seems to be little doubt that F. FAVONIUS ONTARIO expanded its range several hundred kilometers to the Northeast in the last half of the 20th century. In general though these butterflies are often localized around their foodplants. While there are no real data it does seem likely that 2 kilometers is more than enough to effectively separate populations. Note however that most of these species feed on a dominant or co-dominant tree or shrub and so large blocks of contiguous habitat are likely to be fully occupied. Occurrences several kilometers in one or more dimension are common for some of these species, and few occurrences (perhaps not really any for most species) for any are much less than 50 hectares. Territorial males may be much more localized than females are. Both sexes may also be highly concentrated at times on scarce nectar flowers. It would probably be quite unusual for two collections less than 5 or even 10 km apart in suitable habitat to prove to be separate occurrences, but note suitable habitat must include the local foodplant.
Inferred Minimum Extent of Habitat Use (when actual extent is unknown): 1 km
Inferred Minimum Extent Justification: This applies only in extensive essentially contiguous habitats such as often in extensive eastern forest areas. If the habitat patch is smaller and there are no others within a kilometer the inferred extent is that patch. Note that many taxa feed on the dominant or co-dominant vegetation of the canopy or shrub layer and larvae and adults occur widely in such habitats. Many occupied habitats are several thousand hectares and 5-10 km or more in at least one dimension. Still since some of the species (e.g. KINGI, LIPAROPS STRGOSUM, probably CARYAEVORUM) appear to be more local than their foodplants these butterflies should not be inferred present over long distances. A circle of radius 1 km defines an area of about 400 hectares which is well within the range of occurrences where the habitats are large.

Notes: Do not apply these SPECS to S. EDWARDSII or any other species which are obligately dependent on ants to tend their larvae unless the requisite ants are rather ubiquitous species. Such hairstreaks may be extremely localized within large seemingly suitable habitats, being found only near the ant colonies. The Specs for S. EDWARDSII can be consulted for guidance.
