costa
Costa may refer to:

is 33–46 mm. "''0. luteolata'' L. The only European species. The name-typical form has on the forewing red-brown costal markings at the base, at the discal mark and triangularly at the apex; faint, irregularly grey antemedian and postmedian lines, interrupted at the veins. Hindwing with dark discal dot and faint grey postmedian line. — ''aestiva'' Vorh. & Müll.-Rutz is a smaller, more deeply coloured summer brood form. It seems to be the principal or only form in Tunis. — ab. ''flavissima'' Krulik. is almost entirely yellow, only with slight remnants of the costal markings. — ab. ''albescens'' Ckll. has the ground colour pure white instead of yellow. Very pale yellow examples have been separated as ''intermedia'' Harrison. — ab. ''niko'' Chr. is according to. Staudinger an extraordinary aberration with both wings broadly fuscous margined and the basal part of the forewing brownish. Perhaps accidental, as the yellow of this species is highly susceptible to various kinds of chemical action.- ''provincialis'' Ob. is a pale, weakly marked form from Provence. — ''emaculata'' Graes. lacks the apical patch of the forewing. Prevalent in Central Asia, accidental elsewhere. — ''mimulina'' Btlr. has the cell-mark large, the lines strong, the 2 principal lines of the forewing ending in conspicuous red-brown spots on the hindmargin.

The moth sometimes flies during the day but mainly at night, and is attracted to light.
