Adult African rhinoceros beetles are about 4 cm long, dark reddish-brown to black, and the males have a moderately long, rear-curved horn while females have a very short one. They are native to sub-Saharan Africa from Senegal and Chad down to South Africa and are common on coastal areas of Kenya, Tanzania, Mozambique and South Africa, where they attack coconut and oil palms at night. Control methods include burning breeding sites, insecticides, traps with attractants, protective barriers, virus introductions and using the vine Pueraria javanica, which was especially effective in Ivory Coast.

How this page works

This is one bug's fact sheet. The colored box at the top says whether it is dangerous. Sections below cover how to recognize it, whether it is a pest, and how to deal with it. The US map shows which states have records; tap a state to see other bugs there.

Every fact on Bug FAQ comes from a named source (university extension sites, government agencies, GBIF, iNaturalist, Wikipedia). The source is linked next to each section. If we have no source for something, we leave it out.
