These horns are typically found only on males and are used for fighting during mating competitions or for digging. Horned beetles belong to the family Scarabaeidae and include species such as the rhinoceros beetle, elephant beetle, atlas beetle, and Japanese rhinoceros beetle. They are herbivores, feeding on plants, and are harmless to humans as they do not sting or bite.
Two horned beetle
Key features of horned beetles:
Two protruding horns: one on the head and another on the thorax.
Large size, sometimes reaching lengths comparable to a human hand.
Horns are used mainly for male combat and mating rituals.
Found worldwide, including North and South America, Asia, Europe, Africa, and Oceania.
Larvae are grubs that develop in leaf litter, plants, or fallen logs.
A well-known example is the Japanese rhinoceros beetle (Allomyrina dichotoma), which has a large cephalic horn used by males to fight rivals.
In summary, a two-horned beetle is typically a horned beetle species characterized by two distinctive horns on the male’s head and thorax, used for mating competition, and they are harmless herbivores.
