Flightless Dung Beetle, Addo Flightless Dung Beetle Circellium bacchus
Superfamily: Scarabaeoidea. Family: Scarabaeidae. Subfamily: Scarabaeinae

Image
Addo Elephant National Park

Image © nan
Addo Elephant National Park

Description
One of a few flightless dung beetles. Large body (length 30-45mm), black and moderately shiny, globular with rounded outline. Very large pronotum, almaost equal in size to abdomen.

Geographical distribution
This scarab beetle was once widespread throughout South Africa but is now limited to a few pockets of populations, the largest being at Addo Elephant Park in the Eastern Cape Province. Another stable population occurs at the Buffalo Valley Game Farm near Knysna.

Habitat
Fish river scrub and spekboomveld.

Diet
While they are generalist dung feeders, they have a preference for elephant dung but have been recorded feeding on rabbit, baboon, various antelope, human, ostrich and baboon dung/faeces. Feeding might take place at the dung site or a small ball prepared and rolled away and eaten in a protected location. The younger adults usually do this.

Breeding
However, buffalo dung is preferred for breeding. Females produce only one off-spring per breeding cycle, usually one but sometimes two per year so fecundity is therefore low. When breeding, the female removes a portion of dung from the pile, pats it onto a ball and rolls it away, from 7 to 80m, depending on when she finds a suitable site. Unlike other dung beetles, the male trails her by a few centimeters and does not help roll the ball. When the ideal site is decided on, the female excavates the hole and the male then positions himself on top of the dung ball and sinks down with it, the depth varying from 17 to 37 cm. Mating then takes place and the egg is deposited. The male returns to the surface and the female remains with her brood throughout the early (larval) development. This is critical for the survival of the larva as she constantly clears away fungus that develops on the outside of the dung ball. The development time from egg to adult ranges from 120 to 140 days. The young adult then feeds for another 50 to 65 days before becoming sexually mature.

Conservation status
While this species is not included on the IUCN list of threatened species, it complies with most of the criteria and therefore qualifies as "vulnerable". Its vulnerability is attributed to: small, restricted and isolated populations; the habitat is constantly under threat from agriculture and general human encroachment; climate change; low fecundity (breeding capacity); low dispersability as it is flightless; habitat specialisation; co-evolution with and dependence on falling numbers of vertebrates (elephant and buffalo).

Hair Beetle, Carcass Beetle Omorgus asperulatus
Family: Trogidae

Image © nan
Kgalagadi Transfrontier Park

Carcass beetles of the family Trogidae are greyish black, heavily sculptured, small to medium sized beetles. Adults and larvae feed on animal remains and carnivore and raptor faeces. Adults occur underneath the food source and scarab-like larvae in burrows in the soil also underneath it.

Identification
Medium-sized (body length 15 mm). Body, especially abdomen domed. Head and pronotum coarsely punctured, brownish with black raised areas and tubercles, forming a pattern. Elytra black with rows of black tubercles and scattered brownish patches. Legs black, mid and hind tibiae with brownish sections.

Distribution
Free State, Northwest Province and Northern Cape, to Namibia and Botswana; November to April.

Habitat
Arid savannah and desert.

Dung Beetle Copris elphenor, Copris laticornis
Family: Scarabaeidae. Subfamily: Coprinae

Image Male

Description
Copris elphenor, a medium-sized scarab beetle, is approximately 30 mm in length. The body is glossy black in colour, with a strongly punctured surface. The wing covers are glossy black, with distinct longitudinal grooves. The male has a large horn.

Geographical distribution
Widespread in Africa; in Southern Africa it is found in South Africa (eg. Kruger National Park), Namibia, Zambia, Zimbabwe, Mocambique, Angola.

Diet
Herbivore

Behaviour
A large fast burying tunnel species and a pair will bury one dung mass (100-300 g) within 24-48 hours of pad colonization. The male digs tunnels under the dung and fills them with the dung. Females come and lay an egg at each tunnel so that when the larvae hatches it can feed off it.

Hook-winged Net-winged Beetle Lycus melanurus
Family: Lycidae

Image

Image

Net-winged beetles of the family Lycidae are small to medium sized (6-25 mm), orange and black, soft-bodied beetles. The elytra bear intricate network of ridges, hence the name, although the patterning sometimes looks like filigree. The head is almost entirely hidden by the pronotum and the elytra are sometimes broadly expanded and these species look like seeds.
Adults are active by day and occur on various plants and grasses and also feed on nectar. The larvae live in decaying wood and possibly feed on fungi. The orange and black colouration is mimicked by various insects as these animals contain cantharadin and are distasteful to birds and other predators.
Net-winged beetles are all poisonous and therefore display aposematic colouration in combinations of orange and black patterns, which is mimicked by certain long-horn beetles and moths. The longitudinal ridges on the wings are characteristic of the net-winged beetles. They are slow flying insects that are very common on flower inflorescences and flower heads during the summer months. The larvae are predatory on other insects and look very similar to the larvae of the glow worms or fire flies. Eggs are laid under bark and in rotten wood, where the eggs will hatch and the larvae start feeding on other insects.

Description
Lycus melanurus is small to medium with a body length of 11-25 mm. Antennae moderately serrate. Pronotum black, with broad orange lateral borders. Elytra with anterior expansion, produced into backward-pointing hooks; base black at centre, frontal half orange, rear half black.

Habitat
Forest, savannah amd grassland.
