Interestingly, Stictoleptura tesserula is one of the last longhorn beetles occurring in Central Europe where the biology is virtually unknown. The larva of this beetle has never been collected. vácha (in: vácha and Danilevsky, 1988) reared larvae of this species ex ovo from "rotten beach wood". Therefore, the species might be associated with beach woods where it is also frequently recorded. One of the many theories says that larvae of this species might feed underground on rotting roots of the hosts. But it has never been confirmed. The species reaches its western border in Bohemia. The westernmost locality of Stictoleptura tesserula known to us is Hradec Králové (East Bohemia, Czech Republic).
The depicted beetles were collected on flowering goat's beard (Aruncus vulgaris) in Nová Sedlica (NE Slovakia). Collected by M.Hoskovec.
