Pest uses plant hairs for protection

A tiny insect that eats plants has developed a unique strategy to evade its beetle predator: using the plant's trichomes for physical protection. This clever tactic allows the pest to crawl between the plant hairs and feed on cycad sap, while the larger beetle cannot follow suit.
