| The males then try to mate with the labellum or else lift it as they would a female wasp. |
| The labellum indument resembles, although superficially, that of the hairy areas of an insect tegument. |
| These rewards include pseudopollen, wax or a viscid, resinous material secreted by the labellum and floral nectar. |
| It was also noticed that many areas of the labellum surface, especially the median region, are glabrous and smooth. |
| In attempting unsuccessfully to couple with the labellum the male pushes its head forward below the overhanging column. |
| The three-lobed labellum is attached to the column by a column foot, where the nectary is located. |
