Pachyta lamed, a North-Palaearctic boreomontanne species with large area of occurence from Central/North Europe to Japan, has been described from "Europa" as Cerambyx lamed by Carl Linné in 1758 [❖]. In Central Europe, P. lamed is one of the very rare and local inhabitants of preserved spruce stands of medium and higher altitudes. P. lamed larvae feed subcortically in roots of old standing freshly dead conifers (Picea abies is strongly preferred). In oviposition, females prefer free-standing trees with well developed root collars. Pupation after the third overwinterig in the soil at the roots. Adults, active from July to August, can be observed in hot summer weather in flight around host trees or they can be found on felled trees/logs, they do not visit flowers [✧].

Body length:10 - 20 mm
Life cycle:3 years
Adults in:July - August
Host plant:coniferous trees (Picea, Abies, Pinus)
Distribution:almost whole North Palaearctic region (Central/North Europe, North Asia)


The depicted living female beetle was photographed in Podbanské environs (Pribylina, Vysoké Tatry Mts., Liptovský Mikuláš district, Žilina region, Slovakia) on July 29, 2020.
