Family CARABIDiE. 
The “ground beetles,” as the members of this family are popularly 
known, are usually black or dull brown in color, sometimes bronzed or 
metallic, and, exceptionally, usually on flower-loving forms bright blue, 
green and yellow. Many of the species hide during the day under stones 
or bark, among roots of plants, in grass at the base of trees, in burrows 
under ground or in other places of concealment. They fly at night, are 
often attracted to electric light, and in general are predatory in habit. 
The larvrn are more or less fusiform, somewhat flattened above, gray 
or dusky in color, and they live in similar ^localities though even more 
concealed. They also are 
predatory and of decided 
economic importance, feed¬ 
ing upon many of the leaf- 
feeders that go under¬ 
ground to hibernate or to

Curculio larva. adult stage live on plants, 
feed on eggs, caterpillars and slugs of herbivorous forms. 
All the species have slender, filiform antennae, 5-jointed tarsi on all 
feet and are somewhat depressed or flattened; those that live under bark 
sometimes very much so.
