About the New Zealand Giraffe Weevil

The New Zealand giraffe weevil, Lasiorhynchus barbicornis, is a straight-snouted weevil in the subfamily Brentinae, endemic to New Zealand. L. barbicornis is New Zealand's longest beetle, and shows extreme sexual dimorphism: males measure up to 90mm, and females 50mm, although there is an extreme range of body sizes in both sexes. In males, the elongated snout (or rostrum) can be nearly as long as the body. Male giraffe weevils use this long rostrum to battle over females, although small males can avoid conflict and 'sneak' in to mate with females, sometimes under the noses of large males. The larval weevils tunnel into wood for at least two years before emerging, and live for only a few weeks as adults.

Giraffe weevils are common in the North Island. Although rarer, they can also be found in the northwestern South Island, as far south as Greymouth. One has been recorded from the Hollyford Valley in Fiordland. Mitochondrial DNA suggests that during the Pleistocene ice ages giraffe weevils areonly found in the remnant forests of Northland, and have expanded southward during this current interglacial.

It is estimated from how often the New Zealand Giraffe Weevil is recorded against all the insects logged in Egmont National Park (15 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
