Prinobius myardi myardi, a nominotypical subspecies known from France, Spain and Portugal only, has been described from Corsica by Étienne Mulsant in 1842.
Larvae of this polyphagous prionin develops in dead trunks (or branches of a larger diameter) of plethora of deciduos trees. Life cycle at least 3 years. Adults, active from
June to September, are crepuscular/nocturnal and can be attracted by light.
The unclear taxonomic situation within the taxon P. myardi is still debatable and confirmation of the existence/validity of the 5 known subspecies [✧] probably needs further research.
