Fagi is difficult to differentiate from its close cousin, the Rock Grayling (H. alcyone). A more detailed appraisal of the differences (at least as they appear to me) is given on the alcyone page.
These are a selection of undersides showing the variation in the shape of the discal line and hence the difficulty in making an educated identification guess.
Many of the identification rationales are based on the size of the butterfly when seen at the time, plus the clear (or not) area around the ocellus (when visible).
|45839||F||a female engaged in courtship - the male can be seen just above the female. I believe that the open wing and upward-curling abdomen indicates receptiveness.||780|
a female upperside seen during courtship.
|35634||M||a male, taking salts from the ground near a communal rubbish bin.||1060|
|38373||M||a male, fairly typical in terms of the black markings touching the top of the ocellus.||1260|
|41217||M||a male, the unf "eyebrow" touching the top of the ocellus indicates fagi.||1120|
|26368||?||this does not conform to the little bite theory, but the fact that the area around the unf ocellus is not clear, seems to indicate fagi, plus the fact that it was recorded as large at the time.||1000|
a strange underside, compared to the norm, with a very grey post-discal band, where it is normally white or pale, and well-contrasted to the grey areas. Maybe this indicates female. The discal line is quite smooth, without the usual sharp angles, and the bite is the roundest I have ever seen.
less clear, but I feel on balance this is still fagi. Records made at the time indicated it was rather large. Maybe a female on the basis of the heavy-ish irrorations and the lateness of the flight period.
a fagi from the central département of Côte-d'Or, toward the northern end of the range for fagi, and showing and unusually white and broad post-discal band. It was very large, so no doubt that it was fagi.
