Carabus (subgenus)
''Carabus'' is a genus of beetles in the family Carabidae. The genus is highly diverse with 94 subgenera, over 900 species and 2300 subspecies, thus is the largest genus in the subfamily Carabinae. The vast majority are native to the Palearctic, but 16 Nearctic species are also known. ''Carabus'' species are long, and most species are wingless and often very colourful. These are nocturnal, predatory beetles that feed on snails, earthworms, and caterpillars. Most ''Carabus'' species were thought to have inhabited the Eurasian forest, but their low dispersal abilities altered the distribution of lineages within the genus. Diet Adult ''Carabus'' feed on both small live and dead animals such as slugs, snails, earthworms, and insects in all stages, sometimes dead vertebrates. The ways of feeding on snails are different for their adaptations, as macrocephalic beetles feed snails by crushing shells, and stenocephalic beetles feed snails by inserting the head into the shell.

Nocturnal
Nocturnality is a ethology, behavior in some non-human animals characterized by being active during the night and sleeping during the day. The common adjective is "nocturnal", versus diurnality, diurnal meaning the opposite. Nocturnal creatures generally have highly developed senses of hearing (sense), hearing, olfaction, smell, and specially adapted eyesight. Some animals, such as ferrets, have eyes that can adapt to both low-level and bright day levels of illumination (see metaturnal). Others, such as bushbaby, bushbabies and (some) bats, can function only at night. Many nocturnal creatures including tarsier, tarsiers and some owl, owls have large eyes in comparison with their body size to compensate for the lower light levels at night. More specifically, they have been found to have a larger cornea relative to their eye size than diurnal creatures to increase their : in the low-light conditions. Nocturnality helps wasps, such as ''Apoica flavissima'', avoid hunting in intens ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
