Gillmeria pallidactyla

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.
