Pollination trap

The structures of pollination traps can include deep tubular corollas with downward pointing hairs, slippery surfaces, adhesive liquid, attractants (often deceiving the insects by the use of sexual attractants rather than nectar reward and therefore termed as deceptive pollination[1]), flower closing and other mechanisms.

The eggs are deposited on wet or moist soils typically on the sides of drains or other surfaces and hatch in less than two days.

A combination of warmth and rancid smell that is emitted in the center of plant creates a perfect bait for the flies.

Adult Euglossine bees look for mates, and their perfume-seeking behavior gives the Cypripedium orchid plant a resource to set up its trap.

To escape the bucket, the bee must crawl up a narrow tunnel, during which the plant attaches pollen sacs onto its back.

This is another mutualistic relationship as orchid bees will be covered in oils to find a mate and the pollen sacs will be delivered to another plant.

[6][7] Species of the genus Cypripedium (lady slippers) of orchids trap insects temporarily to ensure pollination.

Plants in the genus Ceropegia attract pollinating small flies (usually female) in a wide range of families, including Milichiidae, Chloropidae, Drosophilidae, Calliphoridae, Ephydridae, Sciaridae, Tachinidae, Scatopsidae, Phoridae, and Ceratopogonidae, and the pollinaria always attach to their probosces.

[8][9] An analysis of the scents emitted by Ceropegia dolichophylla showed the presence of spiroacetals which are rare in plants and common among insects.
