Rhinoceros beetle larvae7/27/2023 ![]() Princeton University Press: Princeton, NJ, 1997. A Neotropical Companion: an introduction to the animals, plants, and ecosystems of the New World tropics. Chicago: University of Chicago Press, 1983. Females are lighter but can be slightly longer. As an adult it feeds on fruit and sap.Īdults weigh between 18 and 28 g. The cephalic capsules measure 4.4 mm in length and 4 mm in width this small L1 weighs 0. In its younger stages this insect digests decaying wood. The Rhinoceros Beetle larva: on hatching, the larva measure about 8 mm length and 3-4 mm of in diameter. Unfortunately, because many parts of tropical lowlands have been deforested, or at least overcut, the rhinoceros beetle is rare and struggling to survive. This is why Megasoma elephas populations can only live in forest mature enough to have a sufficient number of large, fallen trees. ![]() Meanwhile, a dung beetle weighs up to 3.5 ounces and grows 2.5 inches long. For larvae, a photo of the underside and video of it crawling can help distinguish it from other. The average rhinoceros beetle weighs between 0.2 and 1.2 ounces and measures 3 inches long with its body alone, but larger creatures can weigh up to 8 ounces and 7 inches long. Since trees in the Tropics decay very quickly and the grubs develop slowly, the grubs will become exposed or run out of food unless they are in a large fallen tree. Adult CRB are black, have a horn, and average 2 in length. In the grub, or larval stage, the beetle munches on decaying wood on the inside of a fallen tree. The entire lifespan of the rhinoceros beetle is 3 to 4 years, but approximately 2 of those years are spent as a grub. These large, impressive beetles come from humble means. Males fight over females and feeding sites, but they are not very aggressive otherwise. They grapple with their horns, and the winner is whoever first lifts his opponent off his feet and knocks him over. Two males will approach each other to compete, often in a tree. The hercules beetle (Dynastes hercules) takes second in size compared to the rhinoceros, and the hercules has a second long horn curving down towards the lower one. Many of the most common treatments for curl grubs contain chemicals called anthranilic diamides, which are also toxic to butterflies, moths and aquatic invertebrates. This rhinoceros can fly short distances, although its heavy body makes it rather ungraceful in flight. The light to dark brown rhinoceros beetle can look almost velvety because it has fine, short hairs over the exoskeleton. Females are smaller and do not have such a dramatically adorned head. He has additional, shorter horns that project out from his head, but the long one is used for fighting. The male is unmistakable with his massive size and long, intimidating horn that curves up. The rhino is one of the strongest insects in the world with relation to its body size, and is the largest beetle within countries like Costa Rica. The rhinoceros beetle can be found from southern Mexico down to northern Colombia and northern Venezuela. ![]() In younger stages, it lives inside large fallen trees. Lowland rainforest is suitable for this beetle, but mature forest is required for the beetle to survive. ![]()
