Phraortes illepidus
One of the larger Japanese stick insects, females reaching 82-110mm. Colour runs from green through brown to greyish brown. Its long antennae separate it from Ramulus mikado, and it is common even near towns.
The branch stick insect ranges from southern Hokkaido through Honshu, Shikoku and Kyushu and on into Taiwan. Males measure 65-82mm and females 82-110mm, and the colour comes in green, brown and greyish-brown forms. It is found in sunny secondary woodland and is common even near towns. Its diet is broad, taking cherry, wild rose, evergreen oak and konara oak among others. Long antennae separate it from Ramulus mikado, which has short ones. Several other Phraortes species are known from Japan, some still undescribed, among them P. koyasanensis at 70-74mm for males and 83-89mm for females, and P. miyakoensis from Okinawa to Iriomote. On the name, GBIF treats the name Phraortes illepidus used for this species as a synonym and gives Phraortes elongatus (Thunberg, 1815) as the accepted name.

It ranges from southern Hokkaido to Kyushu, so indoors it can be kept at temperatures that follow the Japanese seasons. Mist the enclosure so the insect can drink droplets from the leaves.
In stick insects generally a female lays between 100 and 1,200 eggs, the eggs resemble plant seeds under a hard shell, and hatching takes from thirteen days to more than seventy, on average twenty to thirty; temperate species lie dormant through winter and hatch in spring.
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.
Most stick insects mature in a few months through five or six moults and live from a few months to at most three years, depending on the species.
It is easily confused with Ramulus mikado, so check the length of the antennae. Sources differ on the name, so note that Phraortes illepidus and Phraortes elongatus refer to the same animal. It is native to Japan and on neither the invasive alien species list nor the CITES appendices, but it should never be released outside the area it came from.
