Ref.: Bush et al . (2018) . Location: Tatranská Javorina, Jun.–Jul. 2015 ( Bush et al . 2018 ). Notes: Pyrrhula pyrrhula is parasitised by Philopterus citrinellae (see Price et al . 2003: 213 ; also see above). Considering that Bush et al . (2018: 44) did not discuss the unusual host-louse association they recorded for Philopterus fringillae , we can only speculate if their record is the result of a natural host switching or an contamination during or after collecting the lice.
