Ecology and presence in Slovenia
The species occurs in central, central and southern Europe. H. fankhauseri is trophically linked only to species of the genus Laburnum (in Slovenia to Laburnum anagyroides and Laburnum alpinum). Thanks to systematic inventories by Titovšek (1977), records are available for the whole of Slovenia, except for the NE part (Figure 22). Monogamous and univoltine species. The tunnel system is biramous transversely. Beetle length is 2.0-2.8 mm (Figure 21). The species is a dendrobiont and a secondary saproxyle. It accelerates and shortens the process of dieback and decomposition of damaged specimens of Laburnum species. It increases flora and fauna biodiversity in the forest.
