The Grey Beetle Morimus funereus – Natura 2000 code 1089, Family Cerambycidae
Listed in Annex II of Habitats Directive (U1 – Unfavourable-Inadequate in RO Alpine biogeographical region), Vulnerable according to IUCN RedList ver 2.3). Not mentioned in SDF of ROSCI0208 but included in the latest inventories carried out by the park administration. Estimated in RO Alpine biogeographical region as present in 300 km2.
The adults of this species can be observed in March-September, mostly active at twilight and night hours but can be seen also during the day, depending on climatic conditions. The females lay eggs in the tree trunks, with larvae developing under the bark of decayed wood in the first stage, while in the ultimate stage they develop in the heart of the trunk. The larval development takes 3-5 years, digging tunnels between bark and heart of the trees and also in the wood debilitated by the fungal mycelia. In the project area, Morimus funereus can be found in well-structured forest habitats abundant in dead wood, large standing tree trunks and also in-ground trunks and large logs or large branches.
The species is still considered a pest by forester and during the project, we will build up evidence to reconsider its status by demonstrating efficient concrete conservation measures such as building up of wood piles.
