While cicadas are well-known for sound production via abdominal tymbal organs, it has been demonstrated that some species can produce sounds via stridulation, as well. [9] Stridulation is also known in a few tarantulas (Arachnida), certain centipedes, such as Scutigera coleoptrata, and some pill millipedes (Diplopoda, Oniscomorpha). [10]
Like all Australian theraphosids, and old world tarantulas in general, S. plumipes are shy and reclusive by nature, and defensive if disturbed. The species has a reputation for being calmer than other Australian species. Like most Australian tarantulas, S. plumipes has the ability to make a hissing noise if agitated, known as stridulation.

They produce the stridulation-sound-effect by rubbing the femurs of their first and second pairs of legs. They are a slow-growing species, but can reach a leg span of up to 20 centimeters.
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. [2] As of December 2023, 1,100 species have been identified, with 166 genera. [3] The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas".
If they survive that ordeal, males only live for a few more months after mating, while females can live for 25 years. The park service also stressed that tarantulas are not to be feared: Their ...
During the night, tarantulas remain inside the burrow entrance expecting the arrival of prey. At dawn, the tarantula goes into the burrow. [12] Although A. chalcodes is particularly active at night, it is not strictly nocturnal because they are seen in the upper portion of the burrow early in the day. [8]
