This small inquiline is very common in the familiar terminal 

 pine cone galls of Rhabdophaga strobiloides Walsh. 

 The pale yellowish larvae occur between the bracts of the gall and 

 do not interfere in any way with the development of the species 

 primarily responsible for the gall, though they are usually much 

 more abundant than the larger form. This species was bred very 

 commonly during April from pine cone galls on Salix taken at 

 West Nyack. Walsh states that adults appear from the loth of 

 April to the Middle of May, a second brood emerging the latter 

 part of July to September nth. This species normally has 16 seg- 

 ments in both sexes, though occasionally specimens of the male may 

 have 15 or 17 segments. The species described below is tentatively 

 identified with the one reared by Walsh. 



Description. The slightly mottled, orange colored larva of this 

 species has a bidentate breastbone and is only about .75 mm in 

 length.
