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.
Alaus oculatus can reach a length of about 25–45 millimetres (1.0–1.8 in). [2] They have an elongated body, black in color throughout. The pronotum exhibits a large oval patch of darker scales, framed in white, on each side - the common name of the beetle derives from this feature.
The beetle species stands out within its fauna due to its large body size and metallic-black appearance, especially distinguished by its elytra that extends into a pointed shape. Its dorsal surface is between 8-11mm long and its ventral surface is adorned with stiff bristles. Their heads feature prominent eyes and lines across the forehand.
Once metamorphosis is complete, the insect sheds its pupal skin and undergoes a period of hibernation as an adult beetle until the dry season ends. [2] When the rains begin, the beetle breaks open its cocoon, locates a mate, and the entire life cycle starts over again. The adult beetles feed on materials rich in sugar, especially tree sap and ...
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.
Heteronychus arator (hetero+onychus = 'variable claw', arator = 'ploughman') is a species of beetle in the subfamily Dynastinae (the rhinoceros beetles). It is commonly called African black beetle or black lawn beetle. [1] It is native to Africa and it is an introduced species in Australia, Norfolk Island and the North Island of New Zealand. [2]
Adults are large-bodied and black, with very long antennae; in males, they can be up to twice the body length, but in females they are only slightly longer than body length. Both sexes have a white spot on the base of the wings, and may have white spots covering the wings. Both males and females also have a spine on the side of the prothorax. [2]
The English name is derived from the large and distinctive mandibles found on the males of most species, which resemble the antlers of stags.. A well-known species in much of Europe is Lucanus cervus, referred to in some European countries (including the United Kingdom) as the stag beetle; it is the largest terrestrial insect in Europe.
