Information

UK BAP status: Priority Species
Local status: Become rare. This Bedfordshire species has declined more than any other in recent years, and its remaining sites in the Marston vale must be protected from development. Has almost disappeared from inland English counties, but still present around the coasts.
Size: Medium.
Larval foodplant: A variety of grasses.
No. of broods: Two, sometimes three.
Flight time(s): Early May to mid June. Mid July to mid September. A small third brood is possible in October.
Winter: Larva
Habits: Males patrol, often along a bank, hedge or wall, sometimes one following another, looking for females which are more secretive and less easily found. They are very difficult to approach and are easily put to flight, but may settle again if undisturbed.
Habitats: Unimproved grassland, clay pits, brown-field sites and woodland rides.
