Euschistus euschistoides (Vollenhoven). 



Barber Point, Wanakena, Plains and Conifer. This insect 

 seems to be a general feeder upon many herbaceous plants and 

 sometimes on birch, beech and poplar trees. It hibernates in the 

 adult state. The eggs are frequently parasitized by a small

Euschistus tristigmus (Say). 



This is the most common pentatomid in the vicinity of Cran- 

 berry Lake and is found during the entire summer. It is a gen- 

 eral feeder upon herbaceous plants and also frequently breeds on 

 trees (white and yellow birch, ironwood, poplar, beech and maple). 

 Adults and nymphs have also been collected on the blossoms of 

 wild spiraea {Spiraea lalifoUa Borkh.). Several adults were 

 taken bearing tachinid eggs, but the parasite failed to develop in 

 the laboratory. Hymenopterous parasites have reared from its 

 eggs.
