Ground Beetle (Coleoptera: Carabidae) Feeding Ecology
The Carabidae, or ground beetles, represent approximately 40,000 described species found throughout the world, with most species present in the tropics. There are nearly 2,700 described species in Europe and over 2,000 species in North America. Detailed biological descriptions are available for fewer than 100 species (mostly western European species). Many carabids are easily recognized at the family level. Adults are well-proportioned beetles with pronounced mandibles and palps, long slender legs, striate elytra, and sets of punctures with tactile setae. Many possess an antenna-cleaning organ and mostly pubescent antennae. Many are dark colored, shiny or dull. Some have bright or metallic colors and some are pubescent.
Although carabids possess an easy-to-recognize general body form, they have undergone morphological adaptations to suit the habitat in which they are found. Such modifications have permitted running, burrowing in soil and sand, living under tree bark, climbing plants,...
