Neohirasea japonica
Stout for a stick insect, with many spine-like processes along its back and margins. Almost only females are known, males having been confirmed just three times in Japan, so it is thought to reproduce by parthenogenesis. Its range of food plants is unusually wide.
Neohirasea japonica is stout for a stick insect, bearing many small tubercles along the back and spine-like processes along the margins and midline of the thorax. It measures 55-68mm and is a matt dirty brown overall, varying from yellowish to greenish brown in a way that appears to follow the environment it grew up in. In Japan it is known from Honshu west of the centre, Shikoku and Kyushu, with a record adding Amami Oshima, and abroad from Taiwan and southern China. It is nocturnal, spending the day in roadside hollows, the gaps in stone walls or at the base of its food plants, and emerging after dark to feed. Its food plants are remarkably varied: an observation on Hachijojima recorded thirty species in twenty-one families, spanning both dicots and monocots, with lacecap hydrangea particularly favoured in the wild. Almost only females are known; males have been confirmed just three times in Japan, and the species is thought to reproduce by parthenogenesis.

It occurs from the lowlands to low hills west of central Honshu, so indoors it can be kept at temperatures that follow the Japanese seasons. Mist the enclosure to keep it damp.
Eggs are laid on the ground, apparently dropped at random while the insect is hidden by day or out feeding at night; in captivity one or two a day have been recorded. Adults appear in late July, laying begins in August and continues to late October. The winter is passed as eggs, which hatch from late February, and nymphs are seen through to late July, so the species appears to be univoltine. Since almost all are female, a single insect can carry a line forward.
It is placid, and several of the same species can share an enclosure. Being touched during a moult easily spoils it, so give the container height and plenty of footholds. The spines are defensive and pose no danger in handling.
Adults are seen along mountain paths in late autumn, though one source gives the season as June to November, which suggests a somewhat longer adult life. The winter is passed as eggs, so no adult sees the year out.
There was an outbreak on Hachijojima in which greenhouse ornamentals were badly damaged, the insect was treated as a pest over 140 hectares and pesticides were applied. Its food plants are very wide-ranging, so keep the enclosure secure and never release it outside the area it came from. The eggs look like plant seeds, so check the substrate for them before discarding it.
Beginner. This is a beginner-friendly species. No special equipment or experience is required, and it can be kept successfully with basic care setup.
The average lifespan of Japanese Spiny Stick Insect is Adults 4-6 months. With proper care and nutrition, they can live a long and healthy life.
Japanese Spiny Stick Insect typically reaches 55-68mm (a species list gives females at 57-75mm) as an adult. Size may vary depending on care conditions and individual genetics.
Japanese Spiny Stick Insect feeds on: The leaves of a wide range of plants, some thirty species in twenty-one families, with lacecap hydrangea particularly favoured. Aim for a balanced diet with appropriate feeding frequency.
