[2] As one of the smallest known species of giant wētā, Deinacrida tibiospina grows to only around 30-40mm long, and weigh just 7 grams.

[7] Deinacrida tibiospina live in alpine areas of Kahurangi National Park, located at the North-Western corner of New Zealand's South Island.

[2] The wētā dwell above the tree line in sub-alpine tussock and herbfield zones of mountains,[9] observed at altitudes between 900 and 1500 meters.

[1][7] Populations of D. tibiospina occur at very low densities at scattered localities within the central and eastern areas of what was North-West Nelson Forest Park.

[3] Throughout the day, Deinacrida tibiospina often shelter at the base of tussocks, Astelia, flax and other alpine plants.

[1] In comparison with its close relatives, Deinacrida tibiospina has not received a great amount of conservation work.

[2] A University of Otago study found tracking tunnels were not reliable for monitoring the species because their scarcity and lack of attraction to peanut butter lures results in low counts.
