Oryctes elegans

Oryctes elegans, commonly known as date palm fruit stalk borer, is a species of rhinoceros beetles from the subfamily Dynastinae (family: Scarabaeidae). It is widely distributed in the Near East, including all parts of the Arabian Peninsular, Israel, Iraq, most parts of Iran and parts of Pakistan. O. elegans is similar in morphology and biology to Oryctes agamemnon. Both species have overlapping distribution ranges, are pests of date palms and both belong to the subgenus Rykanoryctes. However, O. elegans is slightly more slender and the foretibia has a ventral, subapical and downward-pointing tooth which is missing in O. agamemnon. Oryctes species usually breed in decaying organic matter, where the larvae develop. This is also the case for the young larvae of Oryctes elegans. However, similar to O. agamemnon, the older larvae can attack the living parts of date palms like the base of the fronds (leaves), the young, soft upper parts of the trunk or the roots. Further, the adult beetles bore into the stalks of the date fruit bunches and the base of the fronds, often causing these to break off.
