Ectoparasites from small mammals from two woodland habitats in southern Sweden were investigated. I466 host specimens were infested by II05 Anoplura, 2249 Siphonaptera, 4636 Gamasina, 8I74 Ixodoidea, and 994 Acariformes. The mean number of ectoparasites per infested host in winter was higher inland than at the coast. The infestation frequency was minimum in winter. The mean number of parasites per infested host was maximum in spring due to an abundance of ticks. The peaks of Anoplura, Siphonaptera and Gamasina occurred in winter, spring-summer, and summer-autumn respectively. More Clethrionomys glareolus were infested by lice than the Apodemus species, while the opposite was the case for the other ectoparasitic groups. Hosts heavily infested by one of the ectoparasitic groups also had comparatively many ectoparasites of the other groups. Adult hosts had more parasites than non-adults except for Gamasina, which dominated on non-adults.
