 The particular shape and color of the sun orchids mimics the flowers of lily family (Liliaceae) and the family Goodeniaceae, aiming by deceit for the same insect pollinators.The slender sun orchid ("T. pauciflora") only opens for a short time (or not at all) and is self-pollinating.This self-pollination is a successful strategy followed by several other species such as and "T. circumsepta", "T. graminea ", "T. holmesii" and "T. mucida".
