Group Name: Pyrginae

Use Class: Not applicable
Minimum Criteria for an Occurrence: A location where the species occurs, or recently has occurred, where there is potential for persistence or regular recurrence. Minimally a suitable habitat with the larval foodplant where at least one adult has been verified by a photograph or preferably a specimen. Photographs must be diagnostic and will may need to show both wing surfaces, and there will be circumstances where only a specimen or genitalia examination of one will suffice. Specimens are much easier to obtain. Sight records are not an acceptable basis for a new EO. High quality occurrences will generally support metapopulations.
Mapping Guidance: Consult the habitat and food comments fields for species-specific information on what constitutes suitable habitat when mapping occurrences for individual species.
In very many cases the habitat will be very obviously defined, e.g. eastward a pine barrens or savanna, a ridgeline with many outcrops, a powerline, or multiple foodplant patches within an airport approach zone. Westward metapopulations may be confined to obvious features like a canyon, a stretch of riparian zone or a ridge system. In such cases use the boundaries for the feature supporting the overall metapopulation and it may be useful to map major foodplant patches within these. With a few exceptions such as oak feeding ERYNNIS, most species in this group feed as larvae on plants, usually legumes or mallows, that are typically not community dominants and are often patchy or sparse. So where practical base boundaries on obvious habitat features.

Separation Distance for Unsuitable Habitat: 2 km
Separation Distance for Suitable Habitat: 10 km
Alternate Separation Procedure: When dealing with multiple patches of habitat within an obvious feature like a pine barrens, airport approach zone or powerline, consider all as one metapopulation subject to the suitable habitat distance. On most right of ways or if tthe species is occurring patchily along a riparian corridor, apply the suitable habitat distance unless the foodplant really is completely absent for at least half that distance.
Separation Justification: Most species use small discrete habitats or have patchy foodplant two kilometers across really unsuitable habitat should nearly isolate EOs. However, with marginal habitat use the 10 kilometer figure. On the other hand some adults do wander, especially in summer broods, and even the most localized species seem to be unable to persist long as isolated colonies, but do so mostly as metapopulations. Note the drastic decline of ERYNNIS MARTIALIS and E, PERSIUS PERSIUS eastward, including numerous state extirpations, once they became isolated on a few ridges and small (few hundred hectares) barrens. Even common species such as THORYBES BATHYLLUS often exist in very low densities patchily over large areas and often fail to occupy or persist in small habitat scraps. On the other hand around airports and in right of ways most to all habitat patches are typically occupied at least some of the time. Most Pyrginae are not usually found in dense numbers. These observations strongly suggest much movement and a general need for metapopulations although better data would be desirable, Some occurrences are several kilometers in one or more dimension, even some for rare species such as at least in the 1970s-early 1980s for ERYNNIS PERSIUS PERSIUS in the pine barrens around Concord, new Hampshire and Plymouth, Massachusetts.
Inferred Minimum Extent of Habitat Use (when actual extent is unknown): 1 km
Inferred Minimum Extent Justification: In most cases with taxa likely to be actually tracked and mapped occurrences will be in habitats or remnants of habitats of only dozens to perhaps 100 hectares or occupying discrete patches within larger communities or landscape features and the inferred extent is all available habitat even if this exceeds 1 kilometer. However in cases where the habitat appears extensive or is unclear and information on the occurrence is limited, assume only all suitable habitat within I kilometer radius. Note however if the foodplant is spotty or highly localized never infer an extent greater than that occupied by this plant. In general these skipper will largely occupy suitable habitat where they are present at all, but often one will not really know what suitable habitat really is locally. In extreme cases such as ERYNNIS JUVENALIS and E. HORATIUS, occurrences in the core of their ranges may well be hundreds of thousands of hectares in heavily oak forested regions, such as obviously so for the former in southern New Jersey.
