Orchid's sexual deception triggers ejaculation Male orchid dupe wasp (Image: Esther Beaton) "Few can resist the allure of a beautiful rose, but some wasps outdo even the most ardent flower lover. Presented with the right specimen, a male orchid dupe wasp ejaculates right on the petals."
    "The orchids that caused the most extreme behaviour - pollination with ejaculation - have the highest pollination rate of any known sexually deceptive orchid. I think ejaculation is just a side effect of having an extremely compelling orchid." ~ Anne Gaskett, Macquarie University, Sydney.
These wasps and orchids have a fascinating relationship - visit the article to discover more (including the interesting fact that the female wasps can produce offspring without mating... but only males). There's a video there too, showing the male being fooled by the orchid.

From the page: "Many insects mistake flowers for femmes, but few go as far as these wasps, says Anne Gaskett, a biologist at Macquarie University in Sydney, Australia, who led a study of the insects' amorous intentions toward two species of Australian tongue orchids. "It's just so hard [for the wasps] to resist," she says." Heh. Tongue orchids.
