Clusoides geomyzinus

This species has shown a marked decline during 20th century with only two known recent records from Strathspey. it is closely associated with Caledonian pinewoods and old pine plantations, where the larvae are believed to develop in decaying pine stumps 

Contrary to a common assumption many native pinewoods are not optimal for saproxylic insect populations - there is often not enough natural input of dead wood and cutting and felling have virtually ceased. Many populations occur in plantations outwith protected areas.  C. geomyzinus is a flagship species for conifer stumps where a range of other rare invertebrates and lichens are found. Again these mainly  occur in plantations but are often destroyed by forestry machinery or are treated with antifungal agents. We consider that after a period of research management actions could be identified.

Survey is needed to find any new sites, monitoring is needed to understand the statusgeomyzina%20small.jpg of the species at existing sites, research to understand the autecology and to develop any possible management treatments.  This data is needed to allow reporting against success criteria.
