Family LAMPYRIDtE. 
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 antennae 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.
