In 2013, this was the state of funding for critically endangered invertebrates in NZ, when we translocated 30 ngaio weevils - In 2025, we are getting noticed a little more because lovely conservationists from across the world are voting for the ngaio weevil at shorturl.at/7ZASu Join us!

More introduced plant species on schoolgrounds in Auckland than native species. doi.org/10.1016/j.uf...
Native species add biodiversity & cultural co-benefits than introduced species don't add. Use local species!! 🌏🧪https://iopscience.iop.org/article/10.1088/2752-664X/ad3f22/meta

This is one of NZ's rarest species - the ngaio weevil, browsing on ngaio leaves that are toxic to almost all species. There are only around 300 on one island, Takapourewa in the Marlborough Sounds. Background sound is some of the million seabirds that live on the island.

and 1.3 g for some females, almost as heavy as the smallest mammal!

Thank you. Fortunately, the currents around Takapourewa have stopped introduced rodents arriving, and we now have good biosecurity to help protect them.

This is Takapourewa,an island in Cook Strait, NZ. Home to a million seabirds, 30,000 tuatara, around 250 ngaio weevils, a frog and insect species only found there. Ngāti Koata and DOC work together to protect and restore this amazing place.

New Zealand has a bug of the year - we include the snails, velvet worms, spiders and springtails too - my own favourite is a large flightless weevil, the ngaio weevil.........https://bugoftheyear.ento.org.nz/

Yes, its been up for a few days now....

Entomological Society of NZ has its third celebration of invertebrates beginning today - I will be campaigning for the ngaio weevil, a large (30 mm) flightless weevil found on one island in Aotearoa/NZ bugoftheyear.ento.org.nz

Carabus granulatus, a large predatory ground beetle of fens and wet grasslands. Mowing, grazing & inundation make floodplain hay meadows a challenging habitat for many insects but this is one of the resident species, sometimes present in large numbers.

Necklace Ground-beetle, Carabus monilis. A large predatory carabid w a restricted range in western Europe, this species has declined severely in Britain and is now categorised as Endangered. Although recorded from a range of open habitats, most recent records seem to be from unimproved grasslands.

I am now widening my search area on Takaka Hill to try to get a better grip on its distribution and am planning with Te Papa Atawhai/Department of Conservation to improve its population. Very exciting to be able to work with incredibly rare species like this!

I have been volunteering since 2023 to see if this unassuming ground beetle, Mecodema strictum is still present at Harwoods Hole, NZ, where it has only been recorded eight times. I have now added another eight records by pitfall trapping and ground searching!

Yes, will definitely look out for them!

Frank, are you surveying Canaan Downs? It has a couple of unique beetle species restricted to the area and I am up there for a week in December carrying out a survey for one of them for the Department of Conservation. It could have unique giant springtails too?

I now have 200 pitfall traps in the ground in two locations to monitor TWO nationally critical groind beetle species and two undescribed ones! Photos show the project at Harwoods Hole, near Nelson, NZ, to find Mecodema strictum, seen twice in around 60 years.
