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鈥檚 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鈥檚 life cycle and life form.
A small copper-coloured butterfly. The forewing upperside has a broad brown margin and black spots, whilst the hindwing is brown with an orange margin. The underside forewing is similar to the upperside, and the hindwing is greyish-brown with small dark spots, and the orange spots along the margin are faintly visible. Male and female are similar. Its small size and markings should avoid confusion with other species of the genus. There are two aberrations of this butterfly which are commonly encountered in Corfu. The first which is widely known as the 'Hellenic' form amongst members of CBC, is actually referred to in the scientific literature as ab. fuscae Robs., in which the forewing upperside is almost entirely brown. The second variant which is habitually seen has bright blue spots on the hindwing uppersides and is known as ab. caeruleopunctata Ruhl.

The success of this butterfly is mostly due to its easily replicated, fine scale habitat structure, which usually includes vegetation with small patches of open bare and thus warm, ground.
Knot Grass Polygonum aviculare, Clustered Dock Rumex conglomeratus, Curled dock Rumex crispus, Rumex tuberosus subsp. Tuberosus.
This is a globally distributed species, whose adult butterflies fly fast and low, settling frequently to bask in sunny open spaces. Here they spend a significant portion of their time thermoregulating, enabling them to respond quickly to other insects that may enter their territory. Their highly territorial behaviour is not restricted to insects their own size and they can commonly be observed pursuing butterflies more than twice their dimensions.
