Xanthorhoe fluctuata

Garden carpet

It produces overlapping generations from spring through autumn, so caterpillars and adults can often be found together in the same month.

Size27 to 31 mm wingspan

The garden carpet has greyish white forewings crossed by a dark, broken band that is blackish toward the leading edge and paler toward the trailing edge, with a small pale notch marking the outer edge.

Caterpillars feed on cruciferous plants such as garlic mustard, shepherd's purse, and cultivated cabbages, and the moth produces overlapping generations from spring to autumn, overwintering as a pupa.
