Elateroidea Genera
The Elateroidea are a large superfamily of beetles. It contains the familiar click beetles, fireflies, and soldier beetles and their relatives. It consists of about 25,000 species. Description Elateroidea is a morphologically diverse group, including hard-bodied beetles with 5 abdominal ventrites, soft-bodied beetles with 7-8 ventrites connected with membranes (formerly known as cantharoids), and beetles with intermediate forms. They have a range of sizes and colours, but in terms of shape, they are usually narrow and parallel-sided as adults. Many of the sclerotised elateroids (Cerophytidae, Eucnemidae, Throscidae, Elateridae) have a clicking mechanism. This is a peg on the prothorax which fits into a cavity in the mesothorax. When a click beetle bends its body, the peg snaps into the cavity, causing the beetle's body to straighten so suddenly that it jumps into the air. Most beetles capable of bioluminescence are in the Elateroidea, in the families Lampyridae (~2000 species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Denticollis Linearis
''Denticollis linearis'' is a species of click beetle belonging to the family Elateridae subfamily Dendrometrinae. This beetle is present in most of Europe, in the East Palearctic realm, the Nearctic realm, and the Near East. ''Denticollis linearis'' is quite similar to a Cantharidae species, but it can be distinguished from a soldier beetle by the two basal angles very protruding on pronotum and the deep longitudinal rows of pits. The pronotum varies from orange-red to brownish, the elytra from dark-brown to yellowish, while the head and femora are generally blackish, the tarsi and tibia are orange-yellow. The larvae are omnivorous, feeding on many different plants and other species larvae. The adults grow up to long and can mostly be encountered from May through July in broadleaved and coniferous host-trees. References * Mendel, H. & Clarke, R.
