Orestes shirakii is a species of stick insects native to Taiwan. Only the females of Orestes shirakii are known so far. These are very slim and can reach a length of 50 millimetres (2.0 in). They can be easily distinguished from Orestes guangxiensis by their size. The elongated mesonotum of Orestes shirakii is three times as long as the pronotum. That of Orestes guangxiensis is only 2.5 times as long as the pronotum. The third to fifth tergite of the abdomen in Orestes shirakii lack the posterior lateral tubercles and the shortened posterior edge of the eighth sternite (subgenital plate). The mesonotum is slightly expanded to the rear, the metanotum is rectangular. In the similar Orestes japonicus the mesonotum is parallel and the metanotum is square.
Large parts of Taiwan are named as the range of the species, where it occurs at altitudes below 1,000 metres (3,300 ft). The females begin to lay one to three eggs a week in or on moist soil about six weeks after molting to imago. These take four to six months to hatch. The newly hatched nymphs only begin to eat after about two weeks and take up to 15 months until they are... Wikipedia →

With luck
About 10% of wildlife watchers report an Orestes shirakii sighting in Taipei on a given day, based on 48 verified sightings from GBIF citizen-science data. It is the 213th most-seen of the 765 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May to January
In those months about 10% of wildlife watchers report an Orestes shirakii in Taipei on a given day, against under 5% in February to April, the lowest months.
Only Taipei, in our data
Taipei is the only city on Wallace's Line with enough records to rate Orestes shirakii sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Orestes shirakii is recorded against all the insects logged in Taipei (48 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.
