Philopterus fringillae (Scopoli, 1772)

Host: Pyrrhula pyrrhula (Linnaeus, 1758) .

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.
