The Glowworm. 559 
pery green ; the latter having three longitudinal rows of 
oblong raised spots. All the under part of the insect is 
black. Having only very short wings beneath the cases, 
Nature has providentially supplied it with such legs as 
enable it to run with amazing swiftness. This insect is 
frequently found in damp places, under stones and heaps 
of decayed plants in gardens. There are several spe- 
cies, one of which (Cardbus violaceus) is of a beautiful 
purple. 
The larvae live under ground, or in decayed wood, 
where they remain until metamorphosed to their per- 
fect state, when they proceed to devour the larvae of 
other insects, and all weaker animals that they can 
conquer. 
The Ground Beetles are found as early as the begin 
ning of March, in paths and near old walls, where the 
sun warms the earth with its vivifying beams. Many of 
the large species have been found between the decayed 
baik and wood of willow trees. 
THE GLOWWORM. (Lampyris noctiluca.) 
It is only the female Glowworm which produces the 
beautiful light for which the insect is so well known, 
and she frequently communicates this light to her eggs. 
She is without wings or wing-cases, and possesses no 
beauty when seen by daylight. The male has wings, 
and leathery elytra. The larva is a very ugly and very 
voracious grub, which feeds greedily on snails and 
slugs.
