According to Hartig the larvae live on Pinus sylves- 

 tris socially, each in a nest spun of silk by itself, of a 

 roundish form, and about the size of a hazel nut, plenti- 

 fully garnished with the pellets of frass. Generally 

 the larvae attach their cocoons to the twigs of last year's 

 growth and as a rule near the ground. There are 

 usually two or three or more larvae on the same twig. 

 They are found during July and August and pupate in 

 the earth. The eggs are laid in the needles of last 

 year's growth.
