About
Brachysiderus quadrimaculatus Waterhouse, 1881 is a rhinoceros beetle (Scarabaeidae: Dynastinae) of the genus Brachysiderus. The name quadrimaculatus is Latin for four-spotted, matching the Japanese name yotsuboshi. Waterhouse described it in 1881, and it is illustrated in a plate of Waterhouse's Aid to the identification of insects. GBIF holds about thirty records, concentrated on the eastern Andean slopes and the lowlands at their foot: San Martín, Cusco and Junín in Peru; Morona Santiago, Zamora Chinchipe and Pastaza in Ecuador; and Nariño and Putumayo in Colombia. Little has been published on its size, diet or life history, so care follows general practice for exotic rhinoceros beetles. In Japan specialist shops have handled it, but it is very rarely available, so checking the scientific name is the safest way to buy.

Temperature & Humidity
There is little numeric temperature data. Many records come from the eastern Andean slopes, so keep it away from places where summer heat builds up.

Regulations & Conservation Status
Not CITES-listed
Many live foreign Scarabaeoidea (stag beetles, rhinoceros beetles, flower chafers and relatives) are quarantine pests whose import is banned under Japan's Plant Protection Act, and even importable species require a species-name certificate from a foreign government body under the Invasive Alien Species Act (entry only via designated airports, never by international post). Whether a species may enter must be checked with the Plant Protection Station in advance, so choose domestically bred stock and never release captive beetles.
