Temptress wasps lure from afar
 

Interesting article from ABC Science. Watch out, it could be R rated!
Didn't know that orchids also emit pheromones. I thought it was a purely
visual attraction.

"Female wasps become more sexually attractive as they walk away from orchid
sex traps, according to an international team of researchers.

The results of the study led by PhD student Bob Wong, from the Australian
National University, were published this week in the Royal Society journal
Biology Letters.

The researchers looked at how the south-eastern Australian orchid
Chiloglottis trapeziformis sets up a sex trap for the wasp Neozeleboria
cryptoides."

I've seen this article before but I'm not really surprised that
orchids that rely on pseudocopulation for pollenation release
pheromones. I guess there's no use in Chilloglottis going to the
effort of evolving wasp-like arrangements of calli on their labellums
if they don't smell like the insects in question.
