Cucujus tulliae

Unknown

Overview

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

Cucujus tulliae faces severe population decline primarily due to intensive forest management practices that remove the dead and dying trees essential for its survival. The species requires large-diameter decaying wood in old-growth forests, but modern forestry practices systematically clear deadwood for fire prevention and timber harvesting. Climate change compounds these pressures by altering forest composition and increasing wildfire frequency, further reducing suitable habitat patches.

Threat summary

Habitat

This rare flat bark beetle inhabits old-growth coniferous and mixed forests, specifically requiring large-diameter dead and dying trees with thick bark for larval development. The species depends on decaying wood substrates in mature forest ecosystems, particularly favoring spruce, fir, and pine trees in various stages of decomposition.

Frequently asked questions

Why is Cucujus tulliae classified as Endangered?
Cucujus tulliae 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. Cucujus tulliae faces severe population decline primarily due to intensive forest management practices that remove the dead and dying trees essential for its survival. The species requires large-diameter decaying wood in old-growth forests, but modern forestry practices systematically clear deadwood for fire prevention and timber harvesting. Climate change compounds these pressures by altering forest composition and increasing wildfire frequency, further reducing suitable habitat patches.
Where does Cucujus tulliae live?
Cucujus tulliae occurs in Italy. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
