At least three independent records from different recorders/locations/dates.
Breeds and has its complete lifecycle throughout the year on Corfu. Population is self-sustaining.
Regular immigrant and/or emigrant from Corfu. May also breed but is usually not present all the year around.
Found outside its normal range, such as outside its known habitat. Not enough records to confirm as a Resident or a Migrant.
A species that is expanding its range, but is not self-sustaining, and is reliant on migrants to sustain its population. This is the stage before a species becomes a resident, or a species which is right on the edge of its known distribution.
Records that have not been substantiated and therefore the existence of such a species on Corfu is uncertain.
EU Red Data Status Definitions
Not Evaluated (NE)
A taxon is Not Evaluated when it has not yet been evaluated against the criteria
Data Deficient (DD)
A taxon is Data Deficient when there is inadequate information to make a direct, or indirect, assessment of its risk of extinction based on its distribution and/or population status. Data Deficient is therefore not a category of threat. Listing of taxa in this category indicates that more information is required and acknowledges the possibility that future research will show that threatened classification is appropriate.
Least Concern (LC)
A taxon is Least Concern when it has been evaluated against the criteria and does not qualify for Critically Endangered, Endangered, Vulnerable or Near Threatened. Widespread and abundant taxa are included in this category.
Near Threatened (NT)
A taxon is Near Threatened when it has been evaluated against the criteria but does not qualify for Critically Endangered, Endangered or Vulnerable now, but is close to qualifying for or is likely to qualify for a threatened category in the near future.
A taxon is Vulnerable when the best available evidence indicates that it meets any of the criteria A to E for Vulnerable (see Section V), and it is therefore considered to be facing a high risk of extinction in the wild.
A taxon is Endangered when the best available evidence indicates that it meets any of the criteria A to E for Endangered (see Section V), and it is therefore considered to be facing a very high risk of extinction in the wild.
Critically Endangered (CR)
A taxon is Critically Endangered when the best available evidence indicates that it meets any of the criteria A to E for Critically Endangered (see Section V), and it is therefore considered to be facing an extremely high risk of extinction in the wild.
Extinct in the Wild (EW)
A taxon is Extinct in the Wild when it is known only to survive in cultivation, in captivity or as a naturalized population (or populations) well outside the past range. A taxon is presumed Extinct in the Wild when exhaustive surveys in known and/or expected habitat, at appropriate times (diurnal, seasonal, annual), throughout its historic range have failed to record an individual. Surveys should be over a time frame appropriate to the taxon’s life cycle and life form.
A taxon is Extinct when there is no reasonable doubt that the last individual has died. A taxon is presumed Extinct when exhaustive surveys in known and/or expected habitat, at appropriate times (diurnal, seasonal, annual), throughout its historic range have failed to record an individual. Surveys should be over a time frame appropriate to the taxon’s life cycle and life form.
A largish butterfly with orangey-brown upperside with black spots, and a dull dark-brown underside with a lighter submarginal band. Males and females are similar. The butterfly could be confused for a large dull Aglais urticae, which has a more contrasting underside, and a series of blue submarginal spots on the upperside.

Dan Danahar has found fully grown larvae feeding on European Nettle Tree Celtis australis, in Old Perithia.
Adults are strong fliers and mostly observed in the canopies of trees. The butterfly is territorial and is rarely seen nectaring, instead it prefers to bask on the ground and probe the soil or animal feaces with its proboscis for salts and nutrients. Females seem tend to oviposit on low growing host trees, often young saplings. The larvae are communal until fully grown, frequently highly parasitised, (95%) of larvae maybe hosts. the best time to observe this butterfly is in the early spring or late autumn. The insect overwinters as an adult.
