Ecology and presence in Slovenia
The subspecies is distributed in central and southern Europe. Apart from an old record from Istria (no location and no date), which is not certain to be from Slovenia, the only record was made in the insectarium of the BFG entomological laboratory in 2021. The material (Fraxinus sp. stems) was probably collected in Notranjska. The host species include Fraxinus excelsior and F. ornus. L. wachli orni has an annual generation, overwintering adults. The tunnel system consists of transverse maternal gallery, which can also be oriented longitudinally on thinner branches. Adult length is 2.5-3.1 mm. The body of the beetle is ovoid, matt, densely covered in darker and lighter scales. The elytra are dominated by white scales. If pink scales predominate, it is another subspecies, L. wachli wachtli Reitter, 1887, which has only been found in France.
