Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Xylotoles costatus faces severe population decline primarily due to deforestation and habitat fragmentation across its limited range in Southeast Asian tropical forests. The species' dependence on specific host tree species makes it particularly vulnerable to selective logging practices that target commercially valuable timber trees. Agricultural expansion and palm oil plantations have further reduced available habitat, while the beetle's poor dispersal ability prevents recolonization of degraded areas.

Threat summary

Habitat

This longhorn beetle inhabits primary and secondary tropical rainforests of Southeast Asia, where it depends on specific hardwood tree species for breeding and larval development. The species requires intact forest canopy and is particularly associated with mature trees that provide suitable bark conditions for egg-laying and larval galleries.

Frequently asked questions

Why is Xylotoles costatus classified as Endangered?
Xylotoles costatus is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Xylotoles costatus faces severe population decline primarily due to deforestation and habitat fragmentation across its limited range in Southeast Asian tropical forests. The species' dependence on specific host tree species makes it particularly vulnerable to selective logging practices that target commercially valuable timber trees. Agricultural expansion and palm oil plantations have further reduced available habitat, while the beetle's poor dispersal ability prevents recolonization of degraded areas.
Where does Xylotoles costatus live?
Xylotoles costatus occurs in New Zealand. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Xylotoles costatus?
The main threats to Xylotoles costatus 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.
