The larva was bred from Pyrus aucuparia by 

 Brischke. The leaf is rolled down on either side, or 

 the three upper leaflets are spun together, the larva 

 living between them. It is clear bluish-green, darker 

 on the back through the food shining through. On 

 the underside of the anterior segments are, on each 

 side, a black streak reaching to the first pair of legs ; 

 the spiracles are clear bluish-yellow, cerci brownish at 

 the point. Head very shining, reddish-brown, antennae 

 clear reddish-brown with yellow rings at apex of 

 clypeus, and the lower parts of the face, a spot on front 

 and one on the vertex leading to the neck, black.

 the leaves of Salix caprsea and Populus tremula. The 

 larva from the latter had a bright green-ground colour, 

 darker on the back, there was a black streak on the 

 thorax as in the larva just described, the head shining 

 black, with bright reddish-brown vertex, and the 

 antennas were brown, ringed with black. The Salix
