  Beetles of North America - Cirrus Digital Imaging
Beetles are the dominant form of life on earth: one of every five living species is a beetle, and one fourth of all animals are beetles.
The name coleoptera means "sheath wings." Most beetles have large prominent compound eyes, and there are many different types of beetle antennae: threadlike, clubbed, antennae with leaf-like structures at the tip, so-called longhorn beetles with antennae up to 2 1/2 times their body length.
Since beetles are cold-blooded, their body temperature is usually insufficient to to permit the wing muscles to move rapidly enough for flight.

Adult ground beetles, referred to as "Carabids," are 1/16 to 1-3/8 inches (12 to 35 mm) long, somewhat flattened, sometimes elongate, with threadlike antennae (11-segmented), narrow head (projects forward), and hard wing covers meeting in a straight line at the center of the back with numerous fine, parallel ridges running lengthwise.

 Blue ground beetle - Carabus intricatus: More Information - ARKive
The blue ground beetle is associated with damp, rotten moss-covered wood in mature beech and oak woodland.
The beetles seem to be active throughout the year and a fully-grown larva has been found in summer.
As much still remains to be discovered about the beetle's full life cycle, the current theory for its decline suggests that loss of appropriate woodland conditions, over-vegetation of the woodland floor and lack of suitable grazing may have contributed to its rarity.
