Goliathus albosignatus albosignatus

Goliathus albosignatus is a species of beetle of the family Scarabaeidae, described by Carl Henrik Boheman in 1857. It is one of several species of Goliath beetles that inhabit Africa, but it is the only one exclusively found in subtropical sections of the continent. [1]

Contents

Description

Goliathus albosignatus can reach a length of about 45–70 mm (1.8–2.8 in) in males, and about 40–50 mm (1.6–2.0 in) in females. [2] There are distinctive non-uniform bands of black that stretch horizontally across their elytra to differentiate it from other species. While Goliath beetles are among the largest beetles on Earth, this is the smallest of the species in this genus and not as commonly found as the others. [3] Sexually dimorphic traits are also present in Goliath beetles and include males having a Y-shaped horn protruding from their head to assist with confrontation between males, while in females the horn is absent and their wedge-shaped head is fit for digging the burrows where eggs are to be laid. [4]

Biology

Development of Goliathus albosignatus is carried out in hyrax dung, a trait shared with Fornasinius species, but which does not occur among any other Goliath beetles. [5] Their diet consists of high protein as larvae, but after pupating into adulthood, they have been known to feed on sap from Acacia . [4] [6] Other behaviour of note is that they will gather specifically on marula trees. [6]

Taxonomy

Goliathus albosignatus is taxonomically separated from the other species in Goliathus according to barcoding analysis results that were published in Entomologia Africana in January 2020. Characteristics differentiating Goliathus albosignatus that are mentioned include "hammer-shaped post-clypeal horns of the male, the elongated tarsi, and the presence of cretaceous marks on the pygidium". [5]

The tree resulting from the analysis is listed below:

The family Scarabaeidae, as currently defined, consists of over 35,000 species of beetles worldwide; they are often called scarabs or scarab beetles. The classification of this family has undergone significant change. Several groups formerly treated as subfamilies have been elevated to family rank, and some reduced to lower ranks. The subfamilies listed in this article are in accordance with those in Catalog of Life (2023).

<span class="mw-page-title-main">Japanese rhinoceros beetle</span> Species of beetle

The Japanese rhinoceros beetle, also known as the Japanese rhino beetle, the Japanese horned beetle, or by its Japanese name kabutomushi, is a species of rhinoceros beetle. They are commonly found in continental Asia in countries such as China, the Korean peninsula, Japan, and Taiwan. In these areas, this species of beetle is often found in broad-leaved forests with tropical or sub-tropical climates. This beetle is well known for the prominent cephalic horn found on males. Male Japanese rhinoceros beetles will use this horn to fight other males for territory and access to female mating partners. Upon contact, males will attempt to flip each other onto their backs or off of their feeding tree. In response to selective pressures, smaller male A. dichotoma have adapted a "sneak-like behavior". These smaller beetles will attempt to avoid physical confrontation with larger males and try to mate with females.

<i>Goliathus</i> Genus of beetles

The Goliath beetles are any of the six species in the genus Goliathus. Goliath beetles are among the largest insects on Earth, if measured in terms of size, bulk and weight. They are members of subfamily Cetoniinae, within the family Scarabaeidae. Goliath beetles can be found in many of Africa's tropical forests, where they feed primarily on tree sap and fruit. 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. Goliath beetles measure from 60–110 millimetres (2.4–4.3 in) for males and 50–80 millimetres (2.0–3.1 in) for females, as adults, and can reach weights of up to 80–100 grams (2.8–3.5 oz) in the larval stage, though the adults are only about half this weight. The females range from a dark chestnut brown to silky white, but the males are normally brown/white/black or black/white. Goliath beetles, while not currently evaluated on the IUCN Red List, are facing growing conservation challenges across their African range due to habitat loss, over-collection for the international pet trade, and the potential impacts of climate change.

Coprophanaeus ensifer is a large South American species of beetle belonging to the family Scarabaeidae. This species is necrophagous and builds burrows near or on animal carcasses to dismember the flesh of decaying bodies and bring it to its burrow to feed. Both females and males help build the burrow and feed. It is characterized by its iridescent colors and a horn that is similar in shape and size in females and males. It uses its horn to tear apart carcasses and to fight with other individuals, with male-male fighting occurring more often. However, females also fight to determine a variety of characteristics of the opposing male. This species may be of importance in forensic science due to its destructive behavior on decaying bodies, especially in areas of Brazil where homicide rates are high.
