L. illyricum host tree and biology of the preimaginal stages were unknown for a long time, but Pierpaolo Rapuzzi and Gianfranco Sama reported its larval development in the long dead wood of Fagus sylvatica in the presence of fungi and molds (from North Macedonia and Croatia) in 2012 [✧].

Life cycle:2 - 3 years
Adults in:May - June
