Family LAMPYRID^. 



This family contains the "fireflies" and "soldier beetles." They are 

 long, narrow, somewhat flattened species, with soft, leathery wing-covers 

 and a flexible abdomen. The antennas are usually long, the joints more 

 or less obviously serrated and sometimes even flabellate in the male. 

 The interesting feature in a number of the species is the power of emit- 

 ting a phosphorescent light from the tip of the abdomen. This light is 

 entirely in the control of the insects, and varies in color and intensity in 

 the different species. The "glow-worms" that are sometimes seen in the 

 grass or under stones are larvae or wingless females, and these may have 

 luminous points along the sides of the body as. well as at the tip. In the 

 larval stage they feed on snails or on other soft-bodied insects. 



The "soldier beetles" have a more prominent head and narrower tho- 

 rax; but are of the same soft body texture. The larvae are fusiform, flat- 

 tened above and also predatory in habit, feeding upon soft-bodied larvae 

 or grubs when they enter the earth to pupate. They are distinctly useful 

 as checks to a large series of injurious species, including such pests as 

 the plum curculio.
