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,
