Use Class: Not applicable
Minimum Criteria for an Occurrence: A location where this species occurs or has occurred where there is potential for persistence or at least regular recurrence. Occurrences ranked C or higher should support a permanent population. Minimally a specimen of an adult or late instar larvae that has been verified by an expert and was taken in association with suitable habitat. Reliance on photographs is strongly discouraged.
Mapping Guidance: Use suitable habitat distances across marginal habitat like overgrown pine barrens and also in right of ways. Unsuitable habitat distance is more often appropriate over tracts of closed canopy forest. Occurrence boundaries are often, but not always, obvious based on the habitat. Larvae are polyphagous so do not base occurrence boundaries on the plant species a larva happened to be found on.

Separation Distance for Unsuitable Habitat: 2 km
Separation Distance for Suitable Habitat: 10 km
Separation Justification: Most habitats are large pine barrens (defined very broadly here) and apparently such occurrences are extensive. Since such occurrences are normally large it is prudent to assume collections a few kilometers apart in suitable barrens, heathlands, pine flatwoods etc. are a single occurrence. Also since the larvae are polyphagous on several co-dominant shrubs among others there is no reason to expect occurrences to be highly localized within such pinelands or heathlands. Still adults are almost never collected out of habitat--but are actually less easily found than larvae even in good habitats.
Inferred Minimum Extent of Habitat Use (when actual extent is unknown): 1 km
Inferred Minimum Extent Justification: Use with caution. If the habitat is some sort of northern boggy shrubland infer only the immediate habitat up to 400 hectares. In more typical situations use of this radius would define a habitat well within a realistic size range but smaller than many or most. Since the adults can fly well and larvae feed on several to many of the common shrubs (such as scrub oaks, heaths, Rosaceae) there is no reason to suspect that colonies fail to occupy most available habitat when it is extensive, but since there is some doubt this small radius is suggested.

Notes: More than most moths the size of occurrences varies enormously for this species. It can occur in boggy or marshy acid shrub lands either natural or under powerlines where habitats seem to be only a few dozen hectares at most. More often occurrences are extensive heathlands or pine barrens that cover thousands of hectares. It is possible the smaller occurrences are really demes of larger metapopulations. A complicating factor is that adults are nearly impossible to collect by ordinary methods, although larvae are easier.
