Eggs are laid singly on the underside of foodplant leaves and hatch after about two weeks. They are normally laid on cocksfoot ("Dactylis glomerata") but they will occasionally use purple moor-grass ("Molinia caerulea"), false brome ("Brachypodium sylvaticum"), tor-grass ("B. pinnatum") and wood small-reed ("Calamagrostis epigejos"). Larvae also feed on various "Poaceae", "Phalaris arundinacea", "Alopecurus pratensis", "Calamagrostis purpurea", "Deschampsia flexuosa", "Phragmites communis" and "Elymus caninus"., but also on "Festuca", "Triticum", "Dactylis glomerata", "Molinia", "Holcus lanatus", "Luzula", etc.
