fall records do not seem to extend beyond August twentieth, 



though the species might be reasonably expected later than 



this. It is rare and exceedingly local in Maine, and primarily 



a species of oak, maple and beech woods, less often frequenting 



the orchards and trees of city streets, though more apt to be 



seen and reported under these latter conditions. The food 



consists of various species of insects gleaned from the foliage
