Dicronocephalus adamsi
A Dicronocephalus of the Korean peninsula and China. Males of the genus carry antler-like head horns and are called antler horn beetles; these are medium-sized flower chafers of 20-32mm with long front legs.
Dicronocephalus adamsi (Pascoe, 1863) is a flower chafer (Scarabaeidae: Cetoniinae), originally described as Dicranocephalus adamsi; the label of the type specimen at the Natural History Museum, London reads Corea. Dicronocephalus is a mainly Asian genus in the tribe Goliathini, alongside the Goliath beetles, and is the type genus of the subtribe Dicronocephalina. Its species are called antler horn beetles, though only males carry the antler-like horns. Unlike the African Goliath beetles they are medium-sized, 20-32mm, with relatively long legs, especially the front pair. GBIF holds more than 1,300 records, concentrated in South Korea (Gyeonggi, Gangwon, the Chungcheong provinces, North Gyeongsang and others) and China (Zhejiang, Beijing, Henan and others), with some from North Korea. This encyclopedia also covers its relative D. wallichi. Much about its keeping and life history remains unclear, so care follows general flower chafer practice. In Japan wild-caught specimens from Geoje Island, South Korea, have been sold by specialist shops.

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.

Adults take fruit or beetle jelly; larvae eat humus-rich substrate
The ideal temperature is unclear, but as a temperate species ranging from the Korean Peninsula to China, keep it away from places where summer heat builds up.
It has long front legs and males carry horn-like head projections. Use a well-ventilated enclosure with climbing wood and perches.
The detailed conditions for breeding this species are unclear. Flower chafer larvae grow in humus-rich soil, so provide a deep layer of well-fermented substrate for laying.
The larval duration and adult lifespan of this species are unclear.
Many flower chafers are species whose live import the Plant Protection Act bans (this species is listed as "not regulated" in the Plant Protection Station database). Importing foreign stag and rhinoceros beetles is regulated by the Plant Protection Act and the Invasive Alien Species Act (species-name certificate), with each species needing clearance from the Plant Protection Station, so domestically bred stock is the safe choice. Never release captive beetles.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
Adams's antler horn beetle typically reaches 20-32mm (genus accounts) as an adult. Size may vary depending on care conditions and individual genetics.
Adams's antler horn beetle feeds on: Adults take fruit or beetle jelly; larvae eat humus-rich substrate. Aim for a balanced diet with appropriate feeding frequency.
