Dorcus miwai
In 3 days ~20% in a week ~40%
Dorcus miwai is a species of stag beetle that is endemic to Taiwan. They are small in size, but may be aggressive when provoked; however, they are not as aggressive as the Dorcus titanus beetles. They can live 1–2 years in captivity with proper care. Dorcus miwai beetles are usually easy to care for in captivity. Their diet mainly consists of fruits and sap from trees. In captivity, beetle jelly from pet stores will readily be accepted. Fruits, such as grapes and watermelons, that are high in water content are not suitable for these beetles, as they may drown.

With luck
About 10% of wildlife watchers report a Dorcus miwai sighting in Taroko National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 315th most-seen of the 447 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.
July
In that month about 20% of wildlife watchers report a Dorcus miwai in Taroko National Park on a given day, against under 5% in August to April, the lowest months.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Dorcus miwai sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Taroko National Park, in our data
Taroko National Park is the only park on Wallace's Line with enough records to rate Dorcus miwai sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Dorcus miwai is recorded against all the insects logged in Taroko National Park (7 verified sightings from 2019 to 2026), 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.
