Craighead (1923) stated that “this species has been reared from dead Acer and Quercus ”. JV found numerous specimens in the outer bark of living Q. velutina from PA: Chester Co., Warwick County Park. The bark on the living tree seemed infested with a fungus, making it whitish and rather soft, despite the fact that the tree appeared in good health and remained as such for several years. Perhaps this is the reason why it was utilized by S. bicolor , and it likely represents an unusual behavior for the species. In agreement with Craighead’ s description, JV also found it in a dead and decaying trunk of Q. velutina .
