Appearance
The wingspan is 27–32 mm. The forewings are suffused with green but may be all white in rare cases. There is a small black rectangular blotch which touches the costa near the base and another larger blotch halfway along the costa. One form has a number of black lines and spots scattered across the wing surface, while form "obliterata" is relatively unmarked. The hindwings are pale greyish with a dull yellowish terminal band. Adults are on wing from May to September.
Food
The larvae feed on ''Solidago'' and ''Aster'' species.References:
