The orchid Ophrys speculum relies exclusively on male wasps of the species Dasyscolia ciliata for pollination. Which of the following statements best explains how this specific pollination mechanism functions?

  • A: The orchids produce nectar that attracts female wasps, which then transfer pollen to other flowers.
  • B: The flowers physically trap male wasps, forcing them to pick up and transfer pollen before release.
  • C: The flowers mimic the visual appearance, texture, and scent of female wasps, leading male wasps to attempt mating and thereby transfer pollen.
  • D: Male wasps consume pollen from the orchids, inadvertently spreading it to other flowers as they feed.

Explanation

Figure 38.1 explicitly states that the flowers of Ophrys speculum resemble female wasps visually and tactilely and release a similar scent, leading male wasps to attempt mating and get dusted with pollen.
