Epiphyll growth on leaves of the grapefruit Citrus paradisi and the understory cyclanth Cyclanthus bipartitus repelled the fungus-growing, leafcutter ant Atta cephalotes from harvesting leaves of these tropical plants. Experimental removal of epiphylls from leaves resulted in 2-3 times more herbivore damage by leafcutter ants as compared to matched leaves with epiphylls. Because of the protection from herbivore damage, host plants may derive a partial fitness benefit from association with epiphylls.
葡萄柚（Citrus paradisi）叶片上的叶附生植物以及林下巴拿马草科植物二裂巴拿马草（Cyclanthus bipartitus）的叶附生植物，会阻止以真菌为食的切叶蚁（Atta cephalotes）采摘这些热带植物的叶片。与带有叶附生植物的配对叶片相比，实验性去除叶片上的叶附生植物会导致切叶蚁造成的食草动物损害增加2至3倍。由于受到免受食草动物损害的保护，宿主植物可能会从与叶附生植物的关联中获得部分适合度益处。
