Larva cylindrical, plump and smooth, with rather deeply 

 divided segments ; pinkish-yellow, the dorsal region some- 

 times a beautiful light pink, paler below ; head chestnut- 

 brown with darker jaws ; dorsal plate very pale brown with 

 a crescent-shaped blotch behind each lobe of the head;

September till December in the root-stocks of Senecio 

 jacobcva (ragwort), when young feeding on the outer skin 

 and making covered ways meandering about the root-stock 

 constructed of silk and frass or having a little chamber in 

 the end of the burrow in which it lies when not feeding ; 

 afterwards penetrating to the middle of the root-stock and 

 feeding on the pith. Ultimately eating its way out of the 

 plant, to spin up among rubbish on the ground, and there 

 to lie unchanged until the spring.
