Description and ecology

T. subulata has a body length of around 9 to 15 mm; its colour is varied, from light grey to very dark or reddish brown. It usually has well-developed wings and if scared may fly away readily.

This species frequents mainly wet places: moist grasslands near streams, riverbanks and mudflats, but it is also sometimes found in drier places.[2]

Before mating, the male and female communicate with visual signals. When a male detects a female, he approaches her step by step with a hesitant waggling gait. If the female is mating, she responds to the male's approach by moving her hind legs up and down. Adults lay eggs from August and may be found from June-July of the following year.
