The tannid wasps (flower wasps)
Thynnidae are a family of large solitary wasps whose larvae parasitize the larvae of beetles, especially scarabs.
Females, of course, are searching for beetle larvae. Males feed on nectar and are secondary pollinators.
In this video you can watch how orchids deceive male wasps by pretending to be their females! The male rushes to the flower, and... All covered with pollen! Then he flies to another deceptive orchid, and... Everything repeats again.
This is how this wasp Casanova transfers pollen from orchid to orchid... What a deception! Interestingly, from a human point of view, the similarity between a flower and a wasp is small - but wasps see in a different spectrum and everything is different for them!
