In regard to other insects, Judd finds that Epicauta (blister beetle) 

 with its irritant lluid, is immune from all but the kingbird; Cyllene 

 seldom occurs in the stomachs of birds; May flies and caddis flies, 

 however, are terribly persecuted, but swiftly flying Dipteraand Odonata 

 are highly immune. 



From such facts as these, Judd properly infers, "not cases of protec- 

 tion and non-protection, but cases of greater and lesser efficiency of 

 protective devices. "
