Common name: Arabian Rhinoceros Beetle
Scientific name: Oryctes agamemnon arabicus
Family: Scarabaeidae (Subfamily: Dynastinae)

Size:
Body length: 25–45 mm

Identification:
A large, robust rhinoceros beetle with a glossy dark brown to black exoskeleton. Males possess a prominent curved horn on the head used in combat with rival males, while females have only a small bump or rudimentary horn. The body is oval, heavily armored, and the forelegs are adapted for digging.

Habitat:
Date palm plantations, oases, agricultural land, gardens, and desert areas where palms occur. The larvae develop in decaying palm trunks, rotting roots, and organic debris.

Status in the UAE:
Native resident and widespread in suitable habitats across the UAE. It is particularly associated with cultivated date palms.

Diet:
Larvae feed on decaying organic matter, especially decomposing palm wood and roots. Adults feed little and may consume sap or soft plant material.

Behavior:
A nocturnal beetle attracted to artificial lights. Adults emerge mainly during the warmer months and are powerful fliers despite their heavy appearance. Males use their horns to wrestle rivals for access to females. The species spends most of its life as a larva underground or inside decaying palm material.

Importance:
Although the larvae normally develop in decaying wood, heavy infestations may damage weakened or stressed date palms, making the species of agricultural importance in palm-growing regions.

Conservation Status:
Not Evaluated (NE)
