Once the insect lands in the correct place, the sensitive trigger flies over, hitting the insect on its back, depositing pollen.The
other photo shows the plant's labellum, a special part which helps to align the trigger to sit in its correct position.Size: Approx 1 cm (< 1/2 inch)Note: There are over 300 Stylidium species in Western Australia. Many of them are unnamed.
