This Is the family of the far 

 famed "doodle bug." The larva 

 makes a funnel-shaped pit In dry 

 sand or soil In a protected place, 

 then lies burled at the bottom of 

 Its trap waiting for some passing 

 ant to slide down the "funnel's" 

 side. As the story goes they may 

 be called up into view by repeat- 

 It should be remarked, hov iver, 

 that the performance must be entered Into with such enthusi- 

 asm that some sand or other particles are blown or knocked 

 down the side of the trap, then the "doodle bug" comes out to 

 catch the ant It would normally find.
