Ground Beetle (Carabidae, Carabus Finitimus (Haldeman)) (33310032166)
Ground beetles are a large, cosmopolitan family of beetles, the Carabidae, with more than 40,000 species worldwide, around 2,000 of which are found in North America and 2,700 in Europe. As of 2015, it is one of the 10 most species-rich animal families. They belong to the Adephaga. Members of the family are primarily carnivorous, but some members are herbivorous or omnivorous. Description and ecology Although their body shapes and coloring vary somewhat, most are shiny black or metallic and have ridged wing covers (elytra). The elytra are fused in some species, particularly the large Carabinae, rendering the beetles unable to fly. The species ''Mormolyce phyllodes'' is known as violin beetle due to their peculiarly shaped elytra. All carabids except the quite primitive flanged bombardier beetles (Paussinae) have a groove on their fore leg tibiae bearing a comb of hairs used for cleaning their antennae.

Carabus Auratus
''Carabus auratus'', the golden ground beetle, is a species of ground beetle in the genus Carabus. This species is native to central and western Europe and has been introduced into North America. Description The flightless beetle reaches a body length between 1.7 and 2.0 cm. The elytron, elytra, each marked with three broad longitudinal grooves, are an iridescent gold-green colour, as are the head and thorax. The legs, Antenna (biology), antennae and mouth parts are orange. ''C. auratus'' is found in fields and amongst bushes, particularly on loamy soil. On occasion, it climbs into trees. Active during the day, it preys upon insects, snails, and worms, which it seizes with its Mandible (insect mouthpart), mandibles and sprays with a digestive secretion before consuming it. ''C. auratus'' can be welcome to farmers and gardeners, as it feeds upon pests such as the Colorado potato beetle. The larvae hunt only at dawn. They moult three times before pupation, pupating in the soil an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
