Haaniella erringtoniae is an insect art from the order of the stick insects (Phasmatodea) and a typical representative of the family Heteropterygidae .
features
Both sexes are armed with many sharp thorns on the body and legs. Fore and hind wings are greatly shortened. The sexual dimorphism typical of ghosts is also very pronounced in this species. The slimmer, little patterned to monochrome males are gray-brown to greenish in color and are about 6.5 to 8 inches long. The bright green front edges of the thickened, only one centimeter long front wings, which are here designed as tegmina , are striking . The stronger females reach a length of 8.5 to 11 centimeters. They are reddish brown and beige, or occasionally slightly pink pied. The light-colored bandages on the thighs and two rows of white dots on the ventral side of the abdomen are typical . At the end of the abdomen is the beak-shaped laying spine that is typical for Heteropteryginae species and surrounds the actual ovipositor .
Occurrence and way of life
In Malesia, the species is more precisely native to the Malay Peninsula . The animals found in the west of the island of Sumatra are Haaniella muelleri .
During the day, the animals hide in the leafy layer of the forest floor, where they are very well camouflaged due to their color and body shape. Only at dusk do they climb trees and bushes to feed on the leaves. In case of danger, both sexes are able to make rustling noises with their wings ( stridulation ). In addition, the animals then threaten the attacker with the abdomen raised and the hind legs spread upwards. When approaching further, the rails of the hind legs are quickly struck against the thighs, making the thorns on them very effective weapons of defense.
Reproduction
The females lay their eggs a few centimeters deep in the ground with the laying stinger. With a length of 6.5 millimeters and a width of 5.5 millimeters, these are not even particularly large compared to the eggs of other representatives of this genus . Unlike almost all other Haaniella - species they are not rough and bristled, but smooth, as usual, only the large, lemon-shaped egg from Haaniella saussurei . The cruciform micropylar plate with the clearly visible micropyle in the lower corner of the cross is striking . The life cycle of Haaniella erringtoniae is shorter in each section than that of other species in the genus . After only six months, the first nymphs hatch , which are often adult after another six months .
Systematics
The species was described in 1906 by Josef Redtenbacher as Heteropteryx erringtoniae . He chose the specific epithet in honor of her discoverer Madam Errington. After the species was first transferred to the genus Haaniella , Klaus Günther presented it as a subspecies to Haaniella muelleri in 1944 . Later it was even understood as a synonym of this kind.
A female was deposited as a holotype in the Muséum national d'histoire naturelle in Paris .
Terrariums
The animals, introduced in the early 1990s from the Templar Park in Perak , Malay , were initially distributed in terraristics under the name Haaniella muelleri . Only the comparison with the type specimens showed that the animals kept were Haaniella erringtoniae . All publications published up to 2009 about the animals in breeding thus refer to Haaniella erringtoniae .
The animals prefer temperatures of 22 to 27 ° C and high humidity. In the terrarium they can easily be fed with oak and blackberry leaves. A slightly moist substrate is required to lay eggs, which should cover the floor of the terrarium five to ten centimeters high.
Haniella erringtoniae is listed by the Phasmid Study Group under PSG number 112. There she is still addressed as Haaniella muelleri .
