Geotrupes stercorarius is a species of earth-boring dung beetle. Its common name is the dor beetle, or, the dumbledore, [1] and is common throughout Europe. [2] The beetle is up to 2.5 cm (1 in) long. The whole beetle is weakly lustrous and darkly colored, sometimes with a bluish sheen. The body shape is very compact and arched toward the top.
Adult beetles preferentially colonise older cattle dung, [7] moving between several dung pats as adults. [9] Eggs are laid singly beneath the dung crust [10] and in the underlying soil. [11] Adult beetles typically occur at low densities in mated pairs, [12] and mate-finding and anti-aggregation are thought to be mediated by pheromones. [13]
Other beetles, however, have some decades-old research available, such as dung beetles. For the dung beetle Onthophagus taurus, for example, parental investment in offspring varies based on environmental conditions, especially for males. O. taurus adults provision dung for their offspring in tunnels until the larva matures. Horned males assist ...
Onthophagus taurus, the taurus scarab, is a species of dung beetle in the genus Onthophagus and the family Scarabaeidae. [1] Also known as the bull-headed dung beetle, it is a species that specializes in cattle dung and is widely utilized to maintain clean pastures, making it agriculturally valuable.
Adult beetles are active from early June to late September. They are commonly observed from the droppings of horses and cows and sometimes from human excreta. Ecological niches include both deciduous forests and light forests yachts as well as open spaces. [2] [4] This species was formerly a member of the genus Aphodius. [5]
Dung beetle rolling a ball of dung in the Addo Elephant National Park, South Africa. Dung beetles live in many habitats, including desert, grasslands and savannas, [10] farmlands, and native and planted forests. [11] They are highly influenced by the environmental context, [2] and do not prefer extremely cold or dry weather.
In the long-horned phase, there is an extremely long and slender thread-like horn on head which curves backward. But in short-horned phase, there is a very short transverse tubercle between the eyes. Female beetle has a transverse carina between the eyes on head. [4] Adults are observed from buffalo and cow dung. [5]
A scarab beetle grub from Australia. The C-shaped larvae, called grubs, are pale yellow or white. Most adult beetles are nocturnal, although the flower chafers and many leaf chafers are active during the day. The grubs mostly live underground or under debris, so are not exposed to sunlight.
