The flax weevil (Anagotus fairburni) is a large flightless weevil.[1] It was discovered by E. Fairburn in 1931 on D'Urville Island.[2] The weevil is known to live on New Zealand flax (Phormium tenax), feeding on leaves, where it produces a characteristic feeding notch. The weevil is a large, nocturnal, flightless weevil ranging in length from 20 to 25mm.[3]

Although considered a coastal species, the flax weevil has been found in the Tararua Range on Phormium cookianum, a mountain flax. It is possible that other remnant populations survive in other mountain ranges.[4] However, due to predation by mammals, it is likely restricted to rodent-free offshore islands in more modern times.[3]

The eggs of the flax weevil can take 3 - 5 weeks to hatch. How long a weevil spends as a larva or pupa is unknown but adult flax weevils have lived for over 12 months in captivity.[4]
