Hercules Morishimai

Hercules Morishimai is a subspecies of Hercules beetle found in the mountainous regions of La Paz Department in western Bolivia. Despite its compact build, it has a remarkably powerful frame, and males carry a sturdy horn with a pronounced downward curve at the tip that gives them a striking presence. The glossy sheen of the elytra adds to its visual appeal as light catches it from different angles. Females are solid black, offering a more understated but equally distinctive look.

Hercules Morishimai key facts

Care level: Advanced
Lifespan: Adults 8-12 months
Size: Males 70-143 mm / females 50-60 mm
Temperature: 20〜26℃
Diet: Beetle jelly, banana
Temperature & Humidity: Keep at roughly 20-26 C and avoid Japanese summer heat. From the mountains of western Bolivia; it dislikes stuffy heat.
Breeding & Egg-laying: Females lay in fermented substrate packed 20 cm or deeper. Rear larvae singly in roughly 10 L containers; the larval period is long, 1-1.5 years for females and 1.5-2 years for males, and shortens at higher temperatures.
Cohabitation: Basically mild-tempered, but fights over food, so keep singly. Very rarely a male crushes and kills a female, so never leave a pair unattended.
Lifespan & Rearing Period: Adults live about 8-12 months. Egg to emergence takes 1.5-2.5 years, so patience is needed.
Health & Notes: The thoracic and cephalic horns pinch very hard, so keep fingers clear. A cramped enclosure stresses males and shortens their life. Long-horned males tip over easily, so add footholds.
