Reitterelater dubius

Local name: eksavknäppare

UnknownDDEUDDEU

Overview

Reitterelater dubius is a rare click beetle species characterized by its distinctive metallic bronze-green elytra and elongated body measuring 8-12mm in length. As a saproxylic species, it plays a crucial role in forest ecosystems by decomposing dead wood and serving as prey for insectivorous birds and small mammals.

Reitterelater dubius, the eksavknäppare, is critically endangered primarily due to habitat loss from deforestation and agricultural conversion of its specialized forest ecosystems. The species has extremely limited distribution and small population size, making it highly vulnerable to environmental changes and human disturbance.

Habitat

This species inhabits mature deciduous and mixed forests with abundant coarse woody debris, particularly favoring fallen logs and standing dead trees of oak, beech, and maple species. The beetles require specific moisture conditions found in partially decayed heartwood of large-diameter deadwood in shaded forest understories.
