New Zealand Invertebrates

11005-67002 Knobbled weevil (Hadramphus stilbocarae) pair, mating on host plant Anisotome lyalli after dark. These large flightless weevils are vulnerable to rat predation and now only survive on rat-free islands. The best populations are in Fiordland, on the outer exposed coasts of Resolution Island, Outer Gilbert Island III, Breaksea Island, and Secretary Island. Host plants further south are the megaherbs Stilbocarpa lyalli and S. robusta. Breaksea Island, Breaksea Sound, Fiordland *
