Management Summary Not yet assessed
Population/Occurrence Delineation
Group Name: Tidal Marsh Lepidoptera

Use Class: Not applicable
Minimum Criteria for an Occurrence: An a area of tidal marsh or edge of same (as appropriate for the species) where the species occurs, or has recently occurred, where there is potential for continued occurrence or regular recurrence. Minimally a place where the species has been collected or photographed in or adjacent to suitable habitat.
Mapping Guidance: In mapping habitat strongly consider the foodplant. For example species feeding on edge plants like BACCHARIS, IVA, or in some places DISTICHLIS occupy narrow habitat bands whereas the skippers, DORYODES and others that use the dominant SPARTINA grasses occur throughout the marsh so far as is now known. See the habitat and foodplant comments fields for species-specific information on what constitutes suitable habitats when mapping species in this group.
Separation Distance for Unsuitable Habitat: 3 km
Separation Distance for Suitable Habitat: 10 km
Separation Justification: Both distances are undoubtedly unrealistically small but are chosen to allow some practical separation within huge expanses of generally occupied marshland or edge of same. Note most of these species feed on one or more of the dominant tidal marsh grasses or edge composites and there is no evidence many of them fail to occupy extensive suitable habitats. The only tidal marsh Lepidoptera actually found to sometimes not occupy all "suitable" habitat is PROBLEMA BULENTA and it is not part of this group. All of the skippers in this group routinely fly inland up to at least a half to two kilometers to find nectar and Schweitzer has collected MACROCHILO SANTERIVALIS a half km out of the marshes (in his yard) and EUSARCA FUNDARIA, DORYODES and several of the skippers more than five kilometers out of habitat. All of these observations along Delaware Bay in New Jersey. So obviously of these species are not highly localized.
Inferred Minimum Extent of Habitat Use (when actual extent is unknown): 2 km
Inferred Minimum Extent Justification: If habitat is extensive this is a very conservative figure since many occurrences for these species are several to many square kilometers or they may be nearly continuous along many kilometers of marsh or its edge. If the habitat is well defined and less than 2 kilometers radius or length, inferred extent is simply the entire suitable habitat.
