2012 (CHF): Common and widespread across the whole county with no recent changes in numbers. Before the late 1990s this species was univoltine in Yorkshire with a single brood peaking in late July. Since then it has become bivoltine. The first brood is a couple of weeks earlier and there is an increasingly large second brood in September with records continuing into November. The second generation is significantly smaller and often darker.
