Yarrow Plume
Widely distributed but local, throughout Great Britain.
The Larva is green with the dorsal line darker or somewhat brownish-tinged; subdorsal and lateral grey-whitish.
The Larvae feeds on Yarrow & tansy.
The frontal tuft and palpi are very long.
The posterior tibiae below the middle -spurs are wholly light brown.
The ferruginous-ochreous, clouded with yellow-whitish forewings have a subfalcate apex.
The costal edge is dark fuscous; a darker triangular suffusion on costa beyond middle apex forms a darker dot, and this is followed by a whitish costal spot and an ochreous-whitish subterminal line.
Adults are on wing from June to July.
They become active from dusk onwards.
