This is interesting its a plant that pretends to be ill in order to deter predators from eating it. The plant produces patterns on its leaves which mimic the damage done to plants by mining moths. The picture shows actual mining moth damage on the left and the fake damage right. It appears that moths do not lay any further larvae on leaves that already have damage so they avoid the plants with the fake leaf damage. The idea was tested by painting white correctional fluid on the leaves of some plants to mimic the moth damage. After three the number of leaves affected by the moths were counted comparing green leaves and the pattered leaves. It was found that those with the patterns were significantly less damaged than the plain green ones.
