Orestes japonicus, a stick insect, is a representative of the genus Orestes. 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 adult, they show small dark spots at the base of the abdomen and a larger pair of spots on the metanotum that look like wing stubs. In front of and behind the eyes there are paired, blunt spines. On the tip of the forehead sit two distinct elevations that almost touch each other at the back and move away from each other towards the front. At the rear edge of the mesonotum there is a pair of particularly large tubercles. The 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... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Orestes japonicus is recorded against all the insects logged in Naha (6 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
