On Pacific Islands with no natural enemies of this beetle, the damage can be extreme. Adults damage living palms, either killing the tree due to direct damage, or opening up the tree to fatal damage from other insects or pathogens. It can be also found in betelnut (Areca catchu), Pandanus species, banana, pineapple, and sugarcane. The rhinoceros beetle is considered a major pest of coconut palms (Cocos nucifera) and African oil palm (Elaeis guineensis). Once a coconut palm dies, eggs are laid and the larva/grub can be found. These holes are very noticeable once the frond emerges, with ‘V’-shaped cuts and holes in the midrib. Adults fly at night and chew into the emerging fronds of coconut palms to feed on sap, creating holes in the top part of the palm, and killing the tree if it eats into the meristem (living/growing part of the tree). This pest can also be identified by the damage it inflicts on coconut palms. Larva have a rough head capsule that is large compared to its body. The larval grub is sluggish, white, ‘C’ shaped (2.4-4″ long or more), and crawls on its side. The adult is a stout (1.2-2.4″ long) brownish black beetle with a characteristic horn projecting from the head in both males and females.

Thus, because wandering "like a rhinoceros" sounds more natural than wandering "like a horn," I have chosen the former rendering. However, in a translation, it's necessary to choose one reading over the other. Thus, for example, in Dhp 329 (repeated below), one is told to "wander alone like a king renouncing his kingdom, like the elephant in the Matanga woods, his herd." It's possible that the rhinoceros was chosen here as an example of solitary wandering both because of its habits and because of its unusual single horn. Still, some scholars have noted that while the Indian rhinoceros is a solitary animal, rhinoceros horns don't wander, and that in other verses in the Pali canon, the phrase "wander alone like." takes a person or an animal, not an animal part, for its object. The commentary, however, insists that this term refers not to the animal but to its horn, for the Indian rhinoceros, unlike the African, has only one horn. The text literally says, "Wander alone like a 'sword-horn,' which is the Pali term for rhinoceros. Translator's note: The refrain in this sutta is a subject of controversy.
