Group Name: Noctuid Moths (Default)

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. For almost all species the minimum criteria would be an actual specimen associated with suitable habitat, which includes a substantial amount of one or more larval foodplants. For almost all species an occurrence ranked higher than D should contain a persistent viable population or metapopulation.
Mapping Guidance: If the habitat corresponds to a mappable natural community or other feature consider the boundaries of this feature the EO boundaries. In general EOs need not include more than the breeding habitat and a minimum amount of buffer. In general the larval foodplant should be present on most hectares of the habitat treated as suitable. If this is not approximately true then greater care may need to be taken in defining suitable habitat and actual foodplant stands may need to be considered.
Separation Barriers: Unknown, and probably varies with species.
Separation Distance for Unsuitable Habitat: 2 km
Separation Distance for Suitable Habitat: 10 km
Separation Justification: Most noctuids are strong fliers and except for a few bog and other wetland species (not included here) almost all can be collected occasionally one to several kilometers out of habitat, although some average sized species are long distance migrants. Nevertheless most adults probably stay in habitat most or all of their lives. Two kilometers should generally provide some degree of separation but not create a complete lack of gene flow. If the intervening habitat is mostly suitable there is almost no chance (or even known mechanism by which) two collections a few kilometers apart would represent separate populations but some arbitrary figure is needed. Marginal habitat, for example where the foodplant is relatively scarce (but not absent) should generally be treated as suitable habitat in terms of separation distances.
Inferred Minimum Extent of Habitat Use (when actual extent is unknown): 1 km
Inferred Minimum Extent Justification: In practice for species in this group the inferred extent is usually all contiguous or nearly contiguous habitat which will usually be a few tens to hundreds of hectares. Occurrences are always based on populations which will at least over time occupy available habitat and generally will in any given year. However some arbitrary upper limit is needed with species that typically occupy large habitats. Therefore it is suggested that with really large habitats (usually forests, woodland, brushland) IE be capped at 1 km radius. The resulting 400 hectare area would be a fairly small occurrence for most forest or woodland species. Presence should be inferred only in suitable habitat within this radius.

Author: Schweitzer, Dale F.
Notes: These Specs should generally be applied to non-forest trifid subfamilies, non-migratory Plusiinae, and many Catocalinae whose larvae are either generalists or feed on one or several widely distributed plants. A few other apparently wide ranging species are included.
