Orestes japonicus, a

stick insect, is a representative of the genus Orestes
.

Characteristics

Orestes japonicus is an elongated and strong Orestes species. Males are 38 to 40 millimetres (1.5 to 1.6 in) long. They are almost monochrome, medium to dark brown in color, and when they are freshly

abdomen
is round in cross section. At the rear edge of the eighth abdominal segment there is a centrally located elevation.

Females grow to 44 to 49 millimetres (1.7 to 1.9 in) long and show when fresh adult or as older nymphs the pattern of black spots on vividly combined beige and brown tones, which is also typical for other females of the genus. Their mesonotum is parallel-sided, the metanotum is square. In this it differs from the females of the closely related Orestes shirakii, whose mesonotum is slightly widened to the rear, while the metanotum is rectangular.

The markings of both sexes fade with increasing age and the animals then become increasingly uniformly brown. Under certain conditions, the nymphs can be conspicuously red-brown in color.[2][3]

Distribution area

Orestes japonicus can be found on the

Okinawa Hontō of the main island of the Okinawa Islands.[2]

Taxonomy

Orestes shirakii 'Taiwan'

Orestes sp. 'Tây Yên Tử'

Orestes japonicus 'Okinawa'

Relationships between Orestes japonicus and its
sister species or stocks according to Sarah Bank et al. (2021)[4]

et al (2016)[8] belong to Pylaemenes japonicus according Ho (2016).[2]

As part of the description of six new Orestes species from Vietnam, Joachim Bresseel and Jérôme Constant placed the species 2018 in the genus Orestes.[1][9]

As

Sơn Động District.[4]

Terraristic

The first, and so far only, stock widespread in

Okinawa. He named the specimens thus, following Brock and Okada (2005). The stock was later identified as Orestes japonicus by Bresseel and Constant in 2018.[2][3][9]

Orestes japonicus is easy to keep and to breed. A high

bramble or other Rosaceae are eaten, as well as Gaultheria shallon (salal), hazel, oak, beech, as well as from Epipremnum and other Araceae.[10][11]
