The brushy, yellow protuberances on the lip are also designed to attract pollinators, but they only tempt without providing a reward. To add injury to insult, the flower then snaps closed when a potential pollinator lands on it, and the insect has to crawl out of the tight quarters between the lip and the reproductive parts below in order to escape, hopefully pollinating the flower in the process.
