Both this and the next species are easily flushed from their foodplants during the day.
1 Dry grassland containing perforate st john's-wort (Hypericum perforatum)
2 Dry woodland rides on chalky soil containing perforate st john's-wort and hairy st john's-wort (Hypericum hirsutum)
3 Dry woodland rides on sandy soil containing perforate st john's-wort, slender st john's-wort (Hypericum pulchrum) and trailing st john's-wort (Hypericum humifusum)
4 Wet woodland, rivers, marshes and ditches containing square-stalked st john's-wort (Hypericum tetrapterum)
