The Rhinoceros Beetle is a large insect and can reach lengths of almost 4.5 cm. The length of the 'horn' varies.
These beetles feed off the juice from coconut palm trees, particularly the juice from new shoots. Their larvae feed off compost and other rotting vegetation and are also found in horse manure.
The Rhinoceros Beetle is active at night and is attracted by light which gives you your best chance of seeing one.
They occur over most of South Africa. They are an invasive species in many countries around the world and cause damage to plantations of coconut palms.
