Ixodes passericola Schulze. A description of the hitherto unknown male and larva, with a re-description of the female and nymph

Abstract

During the course of an investigation into the host-relationship of Ixodes hexagonus Leach a large number of birds was examined for its occurrence. These all proved negative for this species, but I. passericola Sch. was present on one robin out of 220 examined, on one starling out of eleven, on seventeen great tits out of 163, on twenty blue tits out of 540, and on four nuthatches out of fifty. A detailed report on this aspect is given later.
