The lying game

sexproxy

Ah, the humble flower. Often surrounded by kin, allies and potential partners, yet always somehow alone. Straining in the wind for a gentle touch, the slightest caress, yet all around surge away as one. What happens when, every time you reach out, all others move aside? Do you dare to hope, to dream, that there is another flower out there, one just like you, one with which to share your thoughts and dreams and aspirations and, most importantly, your gametes?

Just as a shy teenager, crippled by insecurity, might ask a friend to pass a message on to the object of their desire in a school classroom, so plants may harness the power of proxy. Insect pollinators, buzzing from flower to flower with a gametic note attached, are often bribed with food rewards of nectar or pollen as part of this sexy bargain. However, in another parallel with some sullen human adolescents, orchids despise such brazen capitalist tendencies.

Instead, they lure these pollinators, their little sex proxies, with sweetly perfumed and brightly coloured promises of food, promises they will never come good on. But this is not deception enough for some orchids, no. In a cruel twist, they can actually mimic the sex pheromones of the female of a particular insect species, driving the males wild with lust. The orchid’s labellum even imitates the look of the seductive female, tempting the male over to attempt copulation. And as he does so, grinding away in an ultimately fruitless pseudocopulatory frenzy, the orchid gently attaches some pollen to him, to be passed on to the next player in this nefarious reproductive game.

The image above shows the wasp Neozeleboria cryptoides attempting copulation with the “bird orchid”, Chiloglottis valida. The flower mimics the sex pheromone of a female wasp so precisely that the male cannot distinguish between the mimic and the real deal. In one genus of Australian orchids (Cryptostylis), the wasp can even be provoked into ejaculating with the orchid.

You may say to yourself, why sully yourself in such a manner? Why not just pay for this service? And isn’t allowing a wasp to engage in intercourse with you to the point of ejaculation akin to a warped form of bestiality?

To which the orchid would sigh, close its black moleskine notebook, and gaze up at the Che Guevara poster on its wall. Don’t push your human morality on me, man, it says. You just wouldn’t understand.
