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 medium sized white butterfly with black tips to the forewing upperside, and a marbled green hindwing underside. The forewing is very rounded. The males are very distinctive, even in flight, with the large orange-tips to their forewings, and don’t have the yellowish cast of A. damone. The females could be confused with butterflies in the genera Euchole and Pontia, which also have a marbled green hindwing underside. However, they both don’t have a solid black to the forewing.

This species is one very frequently encountered on the edges of various habitats: the boundaries of meadows; the sides of the roads, banks, hedges, ditches and the edges of woodlands. This is inpart because this is where its host plants most commonly grow. For example, the purple flowers of Honesty Lunaria annua help flag up this particular host plant in such locations. This proccupation with linear habitats in the landscape makes it easy for the male butterflies to patrol, backwards and forwards. Thus, ensuring that it has the opportunity to dominate any female entering its territory. This species also shows a preference for relatively damp habitats.
This species has one brood in the spring. Males are territorial and attempt courtship with any females passing through their territory. Females are selective about where they lay their eggs, which are pale creamy green in colour when first laid and as they mature become bright orange. This colour difference allows females to avoid laying their ova on a plant where eggs already have a head start. This is important because larger larvae are cannibalistic and would invariably eat the smaller larvae which hatch from the ova laid by the later females. The mustard oils in many of their host plants make the larvae of this species unpalatable and this is probably true of many other species in the Pieridae family.
