• It is a non-viscid band or strap connecting the pollinia with the viscidium (the viscid part of the rostellum or beak).
• The scolex has a retractable rostellum with four rows of hooks, along with the four suckers that all cyclophyllid cestodes have.
• Alternatively, if there are no pollinia on its back, the insect may move backward, receive a coat of glue from the flower's rostellum, then push open the anther and removing any pollinia present, which adhere to the insect's thorax.
• The stipes connecting the pollina and the adhesive disc (Viscidium) bend in the middle when removed from the rostellum.
• The pollinia lie free on top of the gutter-shaped rostellum, an organ that is filled with viscid fluid.
• Then the moth backs up over a foot and unrolls its proboscis, then flies forward, inserting it into a cleft in the rostellum which leads to the spur while gripping the labellum.

• vogeli contains a scolex, where a hook-filled rostellum is located, and a long neck that attaches to up to six proglottids.
