Eupithecia centaureata ([Denis & Schiffermüller], 1775)
70.1730 (B&F: 1825)
Eupithecia oblongata (Thunberg, 1784)
Resident species, often fairly common and sometimes common at mv light along the downs and coast, but less numerous elsewhere. Probably generally distributed in southern Sussex but perhaps less in the north. Chiefly double-brooded, flying most numerously in two overlapping emergences from early July to mid September, sometimes from late May. Adults have been seen in every week from early April to late October. Larvae have been specifically found on flowers of ragwort, knapweed, yarrow, burnt saxifrage, ornamental garden races of Canadian golden-rod, scabious and lantana. (Pratt, 2011).
