88 LLOYD'S NATURAL HISTORY 



This Moth is common in Central Europe, Asia Minor, and 

 Siberia, but is local and rather scarce in Britain. It expands 

 from three-quarters of an inch to nearly an inch. 



The pattern consists of a mixture of brownish-black and 

 sulphur-yellow. The head, collar and tegulse are sulphur- 

 yellow, bordered with brownish-black, and the thorax is black, 

 with yellow spots. The antennae are black. The abdomen 

 is brownish-grey with yellowish incisions, and the legs are 

 brown, yellowish beneath. 



The Spotted Sulphur Moth. 



The narrow fore-wings are sulphur-yellow, with five black 

 spots along the costa, from the fourth of which runs a narrow 

 blackish band transversely across the wings. This is some- 

 times dusted with yellow, and has a slight metallic lustre. 

 From the base to this line run two straight black bars across 

 the wings, one along the inner margin, and the other above 

 and parallel with the first. The stigmatal area is marked with 

 black spots. Beyond the transverse band is an undulating 

 yellow stripe, and in front of the fringes, which are brownish- 

 black varied with yellow, runs a straight yellow line. The 

 hind-wings are unicolorous brownish-black with white fringes. 



The larva feeds on bind-weed {Convolvulus arvensis). It is 

 usually grass-green, sometimes brown, with a black dorsal line, and 

 a double white line above the legs. The incisions are dark green.
