An article in National Geographic News says of the above photo,
July 17, 2007 — It may look enticing, but this "female wasp" (left) is all stalk.
That's because this temptress is actually a recently discovered hammer orchid, a flower that has evolved to resemble the body of a female wasp. Hapless male wasps are lured to land on — and thus pollinate — the flower.
The orchid is one of six new species found in the biologically rich region of southwestern Australia.
Other orchid species have evolved to use similar cunning to attract male wasps, such as emitting an airborne chemical that mimics a female's pheromone.
One thing that is especially interesting about at least one of these wasp-orchid relationships is that the female wasps emerge a week later than the male wasps so that the orchids do not have to compete with real female wasps in attracting horny male wasps. Another interesting thing is that these relationships confer no benefit on the wasps except free porn. One reference says,
The reward offered is not always food. There is a tropical orchid with flowers that look and smell like females of a certain species of wasp. Males of this species emerge a week before the females. A male who smells a flower of this orchid, think it’s a female wasp, gets closer and the flower looks like a female, lands on it and it feels like a female, tries to copulate, gives up in frustration, and goes on to the next thing that smells like a female, and ends up transferring pollen.
I wonder how the Darwinists can explain that one. The above wasp-orchid relationship is supposedly an example of co-evolution, where two different kinds of organisms exert “mutual evolutionary pressure” on each other. My blog discusses co-evolution here and here.
My thanks to Denyse O'Leary on Uncommon Descent for bringing the National Geographic article to my attention.
