Makara students go ‘behind the scenes’

The students are shown a white-bellied sea eagle.

Back in July, students from Makara Model School had the chance to meet some Te Papa curators and get a ‘behind the scenes’ look at part of our Natural History collection store. This opportunity came about as part of Science Live: Expedition Snares Island that was broadcast earlier in the year. By asking our scientists a question… Read more »

Critters of the Snares Islands

  • A Prodontria longitarsis chafer beetle on Veronica elliptica at night. Image: Alan Tennyson, Te Papa
  • Lyperobius nesidiotes photographed on Anisotome acutifolia on Broughton Island in 1984. A recent survey failed to find its host plant on Broughton Island, the only site where the weevil was known to occur, and so it is possible that this rarest of the Snares Islands’ insects has quietly chewed its way to extinction.

  • Colin Miskelly standing next to a large punui (Stilbocarpa robusta) on the Snares Islands. This plant had leaves up to 73 cm across. Image: Alan Tennyson, Te Papa

A Te Papa team recently visited the Snares Islands Nature Reserve, 105 km south-southwest of Stewart Island, where they completed a range of seabird and plant research projects. Here, Colin Miskelly (Curator Terrestrial Vertebrates) describes some of the smaller inhabitants of the Snares Islands.

Life through a burrowscope lens (Part 4) – subterranean Ohinau Island

Te Papa vertebrate curator Dr Colin Miskelly recently spent 12 days on Ohinau Island (east of Whitianga, Coromandel Peninsula) as part of a Te Papa seabird research team. This blog reports on what the team found living underground on the island. As described in previous blogs in this series, a burrowscope is a high-tech tool… Read more »

Critters of Ohinau Island

  • Close-up of the tusks of a male Mercury Island tusked weta, showing the ridges that are rubbed together to create sound. Image: Colin Miskelly, Te Papa
  • A pair of Mercury Island tusked weta on the forest floor at night, Ohinau Island, January 2014. The large male (with tusks) is on the left; the long appendage at the rear of the female is her ovipositor, used to lay eggs in the soil. Image: Colin Miskelly, Te Papa
  • The entire range of Mercury Island tusked weta. This rare species survived only on 13 ha Middle Island, the small island left of centre in this image. Following eradications of Pacific rats (kiore) on nearby larger islands, they were successfully translocated to Cuvier Island (on the distant horizon), Korapuki Island (immediately below Cuvier Island, and to the lower right of Great Mercury Island), Stanley Island (the large island to the right of Middle Island), the western end of Double Island (which appears as two small islands to the right of Stanley Island), Red Mercury Island (the long, low island on the right), and Ohinau Island (foreground).

  • An adult male Mercury Island tusked wets (Motuweta isolata) on the forest floor at night, Ohinau Island, January 2014. Image: Colin Miskelly, Te Papa

Te Papa vertebrate curator Dr Colin Miskelly recently spent 12 days on Ohinau Island (east of Whitianga, Coromandel Peninsula) as part of a Te Papa seabird research team. This blog reports on some of the more impressive invertebrate species that he found on the island. Ohinau is a 43 ha forested island owned by Ngati… Read more »

Critters of the Poor Knights Islands

  • Purple rock crabs (Leptograpsus variegatus) scavenge the corpse of a Buller's shearwater, Aorangi Island, Poor Knights Islands Nature Reserve. Image: Colin Miskelly, Te Papa
  • Turbott’s weevil (Anagotus turbotti) on ngaio, Aorangi Island, Poor Knights Islands Nature Reserve. Image: Colin Miskelly, Te Papa
  • Flax weevil (Anagotus fairburni) feeding on flax/harakeke, Aorangi Island, Poor Knights Islands Nature Reserve. Image: Colin Miskelly, Te Papa
  • Adult clapping cicada (Amphipsalta cingulata), Aorangi Island, Poor Knights Islands Nature Reserve. Image: Colin Miskelly, Te Papa

Te Papa’s curator of terrestrial vertebrates Dr Colin Miskelly recently visited the Poor Knights Islands Nature Reserve, off the Northland coast, as part of a research team tracking the at-sea movements of Buller’s shearwaters. The project is led by Graeme Taylor of the Department of Conservation, and is intended to identify the marine environments used… Read more »

Critters of Titi Island Nature Reserve, Marlborough Sounds

  • The carnivorous snail Rhytida stephenensis on Titi Island. Image: Colin Miskelly, Te Papa
  • Sarah Jamieson eyeballing one of several holes chewed through her bedroll by ground weta on Titi Island. Image: Colin Miskelly, Te Papa

  • Female Wellington tree weta (Hemideina crassidens) on Titi Island. Image: Colin Miskelly, Te Papa

Titi Island is a 32-ha reserve administered by the Department of Conservation and situated in the outer Marlborough Sounds. The island’s fauna was impacted by introduced Norway rats until these were eradicated in the early 1970s. The island has since been free of all introduced predators. Two species of large flightless insects plus tuatara were… Read more »

Night Life on the Poor Knights Islands

The Poor Knights Islands, northeast of Whangarei, are perhaps best known as a world-class diving location, but the life on land is no less astonishing and it really comes alive at night.  In December 2011, I assisted seabird expert Graeme Taylor with his work on the migration of Buller’s Shearwaters.  This species of petrel breeds… Read more »
