374! NATURE SKETCHES IN TEMPERATE AMERICA 



it frequents the sunny spots, seldom alighting in the shade when 

 flushed. The male stridulates on the wing during short flights, 

 but seldom, if ever, in the more prolonged ones, which it makes 

 when frightened. The note is a harsh droning or buzzing sound 

 somewhat resembling that of a bumblebee, but longer. It is 

 begun after the insect has arisen three or four feet from the 

 ground, and is continued until it begins to descend, being kept 

 up continually while it is flying horizontally. The females 

 usually leap for the first two or three times they are disturbed, 

 but if flushed a number of times they use their wings in endeavor- 

 ing to escape." 



The clouded locust was a common frequenter in the late 

 summer within the weeded area of the old strawberry patch, 

 shown in the foreground of the landscape view depicting the 

 back of our grounds. One can hardly fail to identify this 

 species from the plate photographic illustration containing 

 three figures. The upper and lower individuals are females; 

 the middle figure is that of the male. 



The clouded locust bears the scientific name, Encoptoloplus 

 sordidus. It ranges over the United States and Canada, 

 east of the Great Plains. I have specimens from Kenilworth, 

 Downer's Grove, and Chicago, Illinois; from Oconomowoc, 

 Wisconsin, and from Dune Park and Miller, Indiana. The 

 figures on the plate are from Lakeside, Michigan, and were 

 photographed from living individuals which were posed for 

 the purpose, while in an anaesthetized condition.
