The way some orchids mate can be very convincing.

At the next flower he visits, that same hinge pushes his pollen-covered body onto the stigma, fertilizing it. Some orchids make such convincing mates that insects even ejaculate on them, wasting valuable sperm. But the most vital component of sexual deception is scent: orchids mimic the precise scent of a single insect species. This is possible because many insects and flowers produce simple organic compounds called hydrocarbons, which form a layer that protects their bodies from drying out.
