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 small dark brown, butterfly with white marks on its wings, found on waste ground. Key diagnostic features on are the upperside of the forewing. There are three postdiscal white spots (S6-S8, near the wing tip), and postdiscal white spot in S2 is close to the white spot in S3, which enables separation from the closely related species of M. tessellum. The basal area of the wing has yellowish-grey hairs. The wing margins are chequered. Male and female are very similar. Can be confused with other similar marked skippers in the genera Carcharodus, Muschampia and Pyrgus.

In hot dry grassy stony locations, the host plant can make up the dominant vegetative structure of the habitat and here, this species is often the only butterfly flying.
Jerusalem Sage Phlomis fruticosa.
Dan Danahar believes he has seen P. samia on the island and if this could be confirmed its possible this could also be a host plant for this species of butterfly, although not a significant one.
This skipper dominates many butterfly communities, flying in the blistering heat of mid summer. Many thousands of individuals may be observed at sites where its abundance is high, particualarily in the uplands of the island.
In Corfu it appears to have a wide distribution which most probably reflects the broad distribution of its host plant.
This is a territorial species, with males that perch on Pholomis flower heads, intercepting any flying insects that enter its visual range.
It is curious to watch them slightly turning their heads to scan as much of the their surroundings as is possible, without moving their limbs and or their bodies. Presumably they are awaiting the passage of females through their territories.
