 larvae ; a pentatomid, ants, and coccinellids were minor predators ; 

 hymenopterous parasites of the cocoons were scarce, but shrews 

 consume about 40 per cent of them ; natural enemies account for 

 about 75 per cent of each brood. 



Coleophora laricella. Birds sometimes consume 75 per cent but on 

 the average about 25 per cent of the larvae; ants and pentatomids
