Hesperiinae [subfamilie]
Hesperia [genus] (1/1)
comma [soort]

At present, Hesperia comma is a quite rare resident. The species has been declining steadily since the beginning of the 20th century; the Dutch Monitoring Scheme recorded a moderate decline for the 1990s. There are only 35-45 populations left, and it is now categorised as 'endangered' on the Red List. It is found on dry, nutrient-poor grasslands with open, sandy patches. The caterpillars normally feed on small tussocks of Festuca ovina. Adults may fly as far as one kilometre from the larval habitat in search of nectar. The species flies in one generation from the end of July until the end of August, and hibernates as egg. Eutrophication has led to the disappearance of mosaic vegetation with its varied open structure, resulting in the loss of habitat. Measures, such as extensive grazing, rotational mowing, and possibly small-scale sod cutting to create bare patches, may stop further decline.
