I have examined Zetterstedt's type of T. furibunda. 



E. fatua is very rare in Denmark, only one specimen, a male, 

 is known, taken in earlier time and without particular locality. The 

 species is recorded as bred from Vanessa io, Melitaea athalia and 

 aurinia, Porthesia similis, Euproctis chrysorrhoea and the non Danish 

 Zygaena jausta.
