Hiroshi Fujita, a Japanese collector belonged to Mushi-sha insect shop, described over 20 new subspecies of D. titanus in his book "The Lucanid Beetles of the World". His subspecies included 11 subspecies in Japan alone. Also, he divided D. titanus titanus in the Malay Archipelago into D. titanus yasuokai, D. titanus typhon, D. titanus nobuyukii and others. Fujita's subspecies are in dispute and not widely accepted.

Dorcus titanus is a beetle of the family Lucanidae. It was described by Jean Baptiste Boisduval in 1835. This species is widely distributed in Indonesia, the Philippines, Malaysia, Thailand, Vietnam, Laos, Myanmar, India, Japan, China, Taiwan and Korea.

Dorcus titanus undergoes a complete metamorphosis. Adults can be seen from May to August during the late months of summers to Spring. They tend to feed on sap from trees, what allows them to do so is their large and powerful mandibles with their amazing vitality whenever it comes to rivalry. The main target for Dorcus titanus includes Quercus species of plants. Females lay eggs on the underground among the roots of a matured Oak tree. The eggs hatch within an approximate time period of about a month and the larvae feed on rotten wood as they reside themselves among the roots of the host plant. The larval period lasts about one year it will pupate among the roots and emerge as an adult during early summers. The complete life cycle can last approximately from 1 to 2 years.

Serrognathus titanus (også kjent som Dorcus titanus) er en bille som hører til familien hjortebiller (Lucanidae) i gruppen skarabider (Scarabaeoidea). Den er en av de største hjortebillene, sannsynligvis den aller største om man legger kroppsmassen til grunn. 041b061a72
