Cyrtidula quercus

Unknown

Overview

The Ege-barkplet (Cyrtidula quercus) is a small, cryptically-colored arthropod that inhabits the bark crevices of oak trees, displaying mottled brown and gray patterns that provide excellent camouflage against tree bark. This specialized species plays a crucial role in forest ecosystems as both a decomposer of organic matter trapped in bark fissures and as prey for insectivorous birds and spiders.

The primary threats to Ege-barkplet populations include widespread oak forest fragmentation and the increasing prevalence of invasive bark diseases that alter the microhabitat structure essential for their survival. Climate change-induced shifts in oak tree health and bark moisture levels further compromise the specific microclimatic conditions this species requires for reproduction and feeding.

Threat summary

Habitat

Ege-barkplets are found exclusively in the deep bark crevices of mature oak trees, particularly favoring the furrowed bark of trees over 50 years old where humidity levels remain stable. They require oak forests with minimal human disturbance, where fallen leaves and organic debris accumulate around tree bases to support their complex life cycle.

Frequently asked questions

Why is Cyrtidula quercus classified as Endangered?
Cyrtidula quercus 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. The primary threats to Ege-barkplet populations include widespread oak forest fragmentation and the increasing prevalence of invasive bark diseases that alter the microhabitat structure essential for their survival. Climate change-induced shifts in oak tree health and bark moisture levels further compromise the specific microclimatic conditions this species requires for reproduction and feeding.
Where does Cyrtidula quercus live?
Cyrtidula quercus occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Cyrtidula quercus?
The main threats to Cyrtidula quercus are habitat loss and human disturbance. The full IUCN-classified threat record for this species is detailed on the species page.
