How do thorn bugs disguise themselves?
Thorn bugs are very interesting insects. They are related to leafhoppers and cicadas. They have a horn like pronotum or helmet, which is shaped to resemble the thorns on the branch of a tree.
This projection or thorn helps them to look like a part of the plant they're resting on. Their appearance also discourages predators of both the bugs and the plant from taking a bite, in fear of getting pierced.
The bugs pierce the stem of the plant that they are resting on, and feed on the sap. The excess sap becomes honeydew, which attracts ants. Thorn bugs have fascinated naturalists for a long time because of their unusual shape.
