The caterpillar is greenish with a series of purplish-brown 

 edged, dusky green, Y-shaped marks along the back; above 

 the yellow spiracular line is a row of slanting purplish blotches ; 

 sometimes the general colour is paler, and the markings on the 

 back and sides rosy ; occasionally, the whole of the back is 

 rosy (adapted from Crewe). It feeds on the flowers of knapweed 

 {Centaiij-ea mgra\ scabious, hawkweed {^Hieracimn)^ heath, 

 sallow, etc., etc. : August and September. 



The moth is out in May and June, and is found in woodlands, 

 and on heaths and moors. It is widely distributed over the 

 British Isles.

The caterpillar is reddish brown, paler in some specimens 

 than in others ; a series of blackish spear-head marks along 

 the back, connected by a blackish line, and a dusky Hne on 

 each side ; a whitish line along the spiracles. It feeds, in 

 September and October, on mugwort {Artemisia vulgat'is)^

 put up from its hiding-place among herbage, but at night, 

 when on the wing, it will come to light.
