Eudicella tetraspilota is a beetle from the subfamily of the rose beetles (Cetoniinae). Like other Eudicella species, the species iskeptin terrariums by enthusiasts.

features

The beetles reach a body length of 25 to 40 millimeters. The males are always larger than the females and easy to recognize by their red, y-shaped forked horn, which arises at the head end. The forked head horn is more or less developed in the males of all Eudicella species and is thus typical of the entire genus .

The body of the beetle is green to green-bronze or olive green, occasionally also brown or reddish in color. The color of the pronotum is usually green or green-bronze, but it is very variable and can also be brown, reddish or dark gray-black. The pronotum is roughly dotted and dull, sometimes noticeably roughened. The elytra (or wing cover) are predominantly light to dark brown, usually with a dark point or patch in front (humeral) and near the tip (apical), which are rarely doubled or can be completely absent. The seam of the wing covers has a thin black border. They are indistinctly dotted in rows. On the legs, the thighs (femora) are colored similar to the rest of the body, but they can also stick out red-brown against the greenish trunk. The tibiae (splints) of the hind legs are red-brown, those of the middle and front legs can also be brown or black. The tarsi (limbs) are brown or black. The rear wings are partly crystal clear (hyaline), but almost always have smoky, clouded bands or parts.

The species is quite variable in color and cannot be reliably distinguished from other representatives of the genus solely on the basis of color characteristics. The determination is based primarily on the shape of the head horn in the males. The branches of the forked horn are always flattened in Euthalia tetraspilota . The branches never have serrations. In the subspecies tetraspilota they are long and clearly divergent, their tips pointing outwards or backwards. In the subspecies euthalia they are not very divergent and noticeably shorter.

The larvae reach a body length of up to 55 millimeters.

distribution

The subspecies tetraspilota has been found in Angola , the Republic of the Congo (Brazzaville), the Democratic Republic of the Congo (Zaire), and Zambia . The subspecies euthalia is given for the south of Angola, the east of the Democratic Republic of the Congo, Rwanda and Burundi , Uganda , Tanzania , Kenya , Malawi , Zimbabwe , Mozambique and the north of Namibia ; Information from the Republic of South Africa is doubtful.

Reproduction

The females lay between 50 and 70 eggs, from which the larvae hatch after about a month. These need about 5 to 6 months for their development at temperatures of 25 to 27 ° C before they pupate. After a further one to two months, the fully developed beetle hatches out of the earth. The adults are around three months old. The development time in the terrarium is strongly dependent on the temperature. It takes about 24 weeks at 21 ° C, and only 17 weeks at 27 to 30 ° C.

Systematics

The systematics and taxonomy of the species, like the entire genus, was confused until the revision by the Italian entomologist Michele de Palma in 2009. In his adaptation of the Goliathini tribe , the French Vincent Allard , based mainly on material from breeders and hobby collectors, established numerous subspecies almost exclusively on the basis of coloring characteristics, the justification of which was questioned by the South African Erik Holm in 1993. De Palma presented the " Eudicella smithi " sensu Allard (nec. MacLeay 1838) with a number of subspecies to the nominate form of Eudicella tetraspilota , the Eudicella euthalia of Allard and others as a subspecies of this species Allard Eudicella smithi berterandi Faimaire now belongs to Eudicella tetraspilota euthalia .

A distinction is now made between two subspecies:

  • Eudicella tetraspilota tetraspilota Harold, 1879
  • Eudicella tetraspilota euthalia (Bates, 1881) (original combination of names Ceratorrhina euthalia )

The genus Eudicella in the narrower sense comprises, depending on the view, almost 20 species. If, following Holm's view, the genus Cyprolais is understood as a subgenus, another 10 species are added.
