The portraited specimen of the Plagionotus detritus (upper picture) was reared from larva found in oak (Quercus robur) in Křivoklátsko Protected Landscape Area (Central Bohemia, Czechia).

The beetles in copula (and both mounted specimens) were reared from larvae found under a thick bark of a dead standing oak (Quercus robur) trunk in Zbečno (Central Bohemia, Czech Republic) where the species is quite common (Rejzek and Rébl; ❖). The male of Plagionotus detritus was collected and photographed on an oak log in Zbraslav (Prague, Central Bohemia, Czech Republic).
