Trees in Trouble

When coconut rhinoceros beetle adults feed on a palm tree, they often create zig-zag or diamond-shaped cuts in the palm leaves. This is a good sign the beetles are around.

Image
Image

The large holes seen here are caused by hungry coconut rhinoceros beetles. They burrow into the top of palm trees to feed on the soft tissue in the heart of the palm.

Diamond-shaped patterns in palm leaves mean that coconut rhinoceros beetles are around!
