Hemiandrus pallitarsis is a species of ground weta endemic to New Zealand. This nocturnal species hides in burrows during the day, and can be an important food for kiwi. They can be identified by a single foretibial spine, three prolateral spines, and four retrolateral spines on the mesotibia, and their tibia lacks a tympanal membrane (they hear only through vibrations in the ground). The female has an unusual appendage on her abdomen, and the male has blackened hooks on his last tergite. They have a two-year life cycle, and their diet is largely unknown. Unusually for an insect, the female shows maternal care towards her eggs and nymphs.
Hemiandrus pallitarsis was first described by Francis Walker in 1871 in the genus Libanasa, and in 1906 W. F. Kirby moved it to the genus Ceuthophilus. In 1938, Kjell Ander erected the genus Hemiandrus, and moved this species to it, under the species name furcifer. This species is therefore synonymous with both Libanasa pallitarsis Walker and Hemiandrus furcifer Ander.
Hemiandrus pallitarsis is endemic to the North Island of New Zealand. They are widespread throughout this distribution and are relatively abundant... Wikipedia →

Rare
Under 5% of wildlife watchers report a Hemiandrus pallitarsis sighting in Auckland on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 338th most-seen of the 689 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June and November–January
In those months about 10% of wildlife watchers report a Hemiandrus pallitarsis in Auckland on a given day, against under 5% in February–May and July–October, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Hemiandrus pallitarsis sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Auckland, in our data
Auckland is the only city on Wallace's Line with enough records to rate Hemiandrus pallitarsis sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Hemiandrus pallitarsis is recorded against all the insects logged in Auckland (16 verified sightings), 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.
