Group Name: Breeding Immigrant Lepidoptera

Use Class: Not applicable
Minimum Criteria for an Occurrence: Locations where the species breeds successfully (that is can produce adult progeny) where there is potential for regular recurrence. Minimally a place where the species has been confirmed in association with habitat and larval foodplants early enough in the season that progeny might be produced. In most cases, places where temporary breeding populations occur regularly even though the species cannot persist from year to year, generally due to inability to survive winter. In the extreme southern parts of the range of these species they may occupy some sites permanently but some species may have no permanent populations anywhere. What consitutes regular recurrence will probably be decided locally, but it is strongly recommended that places occupied less than one year in ten never be considered occurrences. It is further suggested that if for some reason defining EOs is deemed useful for globally very common species where they are not resident that only locations occupied more than 80% of years be considered. It is very strongly recommmended that EOs not be defined where a species is considered accidental even if it does occasionally manage arrive early enough to breed. Observations of adults regardless of quantity late in the season (generally September or later in most of North America) should not be considered evidence for EOs without actual evidence that these were locally produced as opposed to being simply immigrants.
Mapping Guidance: While EOs for these species are necessarily arbitrary and often of dubious utility, the best suggestion is to map major local habitats based on known or strongly inferred breeding and regular observations of adults. Most of these are species of open highly disturbed or at least successional habitats and in heavily forested or otherwise more or less "natural" landscapes their habitats should be easily defined, while in agricultural or other severely disturbed areas they will often not be.
Separation Distance for Unsuitable Habitat: 5 km
Separation Distance for Suitable Habitat: 20 km
Separation Justification: These numbers are totally arbitrary and based on the assumption that if these species reach a particular area in a given year early enough to build up substantial populations they will occur widely within it by the end of the season or sooner, and will find and occupy most or all significant foodplant patches as adults move widely over the landscape. These species will almost never be localized in small areas where the foodplant is common and widespread. By definition adults of species in this group can and do move at least hundreds of kilometers, a few even farther.
Inferred Minimum Extent of Habitat Use (when actual extent is unknown): 10 km
Inferred Minimum Extent Justification: The species is either present or it is not, and if it is all local habitats should be occupied to some extent during the season.
