第一段说一个意大利的植物学家发现一直奇特的现象,用了unbelievable这个词,描述了一下这种植物(A什么的lily,这个文章里的意大利学者叫A啥啥,虫子也叫A啥啥,花也叫A啥啥,醉了),靠mimic蘑菇吸引虫子传粉
第二段总结这种mimic
第三段说这种现象在其他植物上也有
The mousetail plant (Arisarum proboscideum) is a member of the arum lily family. This dainty Mediterranean flower has a long tail to its floral chamber. Mushroom gnats act as agents for cross-pollination of the flowers. Most of the mushroom gnats visiting mousetail inflorescences are females. They seek out the small holes and cavities that give the mousetail appendix in spongy appearance. The gnats lay their eggs in these cavities in order to assure their brood of a food sources. The mousetail’s limitation of a mushroom is insurance that it will visited by pollinating insects.
Another example of floral mimicry comes from the mirror orchid (Ophrys speculum). The lip of each mirror orchid flower looks like a miniature blue-steel looking-glass edged with gold and set in a maroon frame fringed with rust-colored hairs. Each part of the lip mimics to perfection a part of a female digger wasp (Campsoscolia ciliata). When male wasps try to mate with the orchid, pollinia become attached to the wasp's body. When the wasp later visits another mirror orchid flower, the purpose of the elaborate deception — pollination — can be achieved. |
