J. J. Reading's Catalogue of the 
Larva No. 1. — Deep green; scattered short bristly hairs; dorsal, 
subdorsal, longitudinal, and transverse lines deeper; spiracles, 
spiracular line and scattered spots, white. 
Larva No. 2. — Same markings as in No. I. ; but the whole 
ground colour is chromish red, inclining to pink. 
The larva No. 2. is found feeding upon the bright petals of Ononis 
spinosa, the hue of which is shed through the transparent skin of 
the caterpillar; whilst No. 2 feeds on the leaves and seeds of 
one or more of its food plants. 
Food plants of the larvcB are : — 
Ononis spinosa and arvensis (merely two forms of one species). 
Occurs commonly along the coast, as well as inland. 
Arenaria rubra, a common rock plant. 
Hyoscyamus niger, Whitsand-cliffs. 
Pyrethrum inodorum and maritimum (both being forms of one 
plant). Common on the coast and near thereto. LarvcR feed 
on the anthers of this plant, like those of Polia serena on a 
similar part of a Sonchus. The larvcB on Pyrethrum are yellowish- 
green, the yellow anthers imparting some of the colouring matter, 
with which they are charged, to the caterpillar ; whilst the pollen 
gives a stronger tinge of the same to the external covering, by 
adhering to the hairs of the insect. 
Full-grown larvce are found in the beginning of August, but 
partially-grown are to be obtained from as early as May, 
App, — September, and in spring and summer. Not double- 
brooded, but semi-brooded twice a year ; one portion coming forth 
soon after the completion of the pupa condition, and the other 
portion, or part of it, remaining in the pupal state till the next 
season ; whilst sometimes it happens that a few keep to the pupal 
covering for one, two, and even three years.
