Goliath beetles can be found in many of Africa's tropical forests, [1] where they feed primarily on tree sap and fruit. [ 1 ] [ 2 ] Little appears to be known of the larval cycle in the wild, but in captivity, Goliathus beetles have been successfully reared from egg to adult using protein-rich foods, such as commercial cat and dog food.
Stenocara gracilipes is a species of beetle that is native to the Namib Desert in southern Africa. This is one of the most arid areas of the world, receiving only 1.4 centimetres (0.55 in) of rain per year. The beetle is able to survive by collecting water on its bumpy back surface from early morning fogs.
Ground beetles are a large, cosmopolitan family of beetles, [2] the Carabidae, with more than 40,000 species worldwide, around 2,000 of which are found in North America and 2,700 in Europe. [3] As of 2015, it is one of the 10 most species-rich animal families.
Pliny the Elder discusses beetles in his Natural History, [158] describing the stag beetle: "Some insects, for the preservation of their wings, are covered with an erust —the beetle, for instance, the wing of which is peculiarly fine and frail. To these insects a sting has been denied by Nature; but in one large kind we find horns of a ...
Eleodes (commonly known as pinacate beetles or desert stink beetles) is a genus of darkling beetles, in the family Tenebrionidae. [1] They are endemic to western North America ranging from southern Canada to central Mexico with many species found along the Mexico-United States border. [2] Some species have been introduced to Colombia.
Buprestidae is a family of beetles known as jewel beetles or metallic wood-boring beetles because of their glossy iridescent colors. Larvae of this family are known as flatheaded borers. The family is among the largest of the beetles, with some 15,500 species known in 775 genera. In addition, almost 100 fossil species have been described. [1]
Nearly all of the 500-odd species are tropical; species found in North America are notable for their size, ranging from 20 to 43 mm, for having a single "horn" on the head, and for a form of social behavior unusual among beetles. Bodies are elongate-cylindrical and black overall; ventral surfaces may be covered with yellow setae.
Scarites subterraneus is a carnivorous beetle. This is clear when looking at its large jaws, which it uses to hunt its prey. [ 7 ] The specific diet of S. subterraneus is not remarkably clear (they seem to be willing to eat any invertebrate in any stage of life), but in captivity they have been observed to eat mealworms .
