Leek Orchids, unlike most other orchids, actually do offer their pollinating insect sustenance.

The nectar containing cells, located on the labellum, have to be punctured in order to reap the reward.  This can be done by a number of different insects, including ants.

Most Leek Orchids have a sweet smell and on warm days this can be quite pungent.  As wasps have a good sense of smell, this certainly encourages the insect to visit the many flowered stem.

The Prasophyllum flower is inverted and the shiny area mid labellum is enticing to various insects which include hover flies, crane flies, beetles, bees and wasps (all of which are potential pollinators).
