Pachysaga strobila

Unknown

Overview

Pachysaga strobila is a species of insect in the family Tettigoniidae. It is endemic to Australia.

Pachysaga strobila, a large flightless predatory katydid restricted to a small area of remnant native forest and shrubland in New South Wales, Australia, is threatened primarily by ongoing clearance and fragmentation of its habitat for agriculture and development. Because it is flightless and confined to a narrow geographic range, isolated populations face heightened extinction risk from localised disturbances such as land clearing, altered fire regimes, and edge effects that degrade the leaf litter and understorey layers it depends on. Invasive predators, including foxes and feral cats, add further pressure on a species already limited by its poor dispersal ability.

Threat summary

Habitat

This wingless katydid occupies dry sclerophyll forest and woodland with dense shrub and leaf-litter cover, sheltering by day in ground debris and low vegetation and foraging nocturnally as an ambush predator of invertebrates.

Frequently asked questions

Why is Pachysaga strobila classified as Critically Endangered?
Pachysaga strobila is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Pachysaga strobila, a large flightless predatory katydid restricted to a small area of remnant native forest and shrubland in New South Wales, Australia, is threatened primarily by ongoing clearance and fragmentation of its habitat for agriculture and development. Because it is flightless and confined to a narrow geographic range, isolated populations face heightened extinction risk from localised disturbances such as land clearing, altered fire regimes, and edge effects that degrade the leaf litter and understorey layers it depends on. Invasive predators, including foxes and feral cats, add further pressure on a species already limited by its poor dispersal ability.
Where does Pachysaga strobila live?
Pachysaga strobila occurs in Australia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Pachysaga strobila?
The main threats to Pachysaga strobila are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
