Certain parasite species have free-living stages, so habitat range may influence host-species range. We tested whether regional occurrence and habitat use of parasitic water mites were related to their host-species range. We collected 7445 Arrenurus

Immune ability and immune expression have been viewed as life-history traits that are influenced by such factors as the likelihood of being parasitized, intensity and costs of parasitism, and trade-offs associated with immune expression. In this pape

Numbers of larval Arrenurus sp. and Limnochares americana Lundblad mites, parasitic on adult males in a population of Leucorrhinia frigida Hagen, were found to be negatively correlated. The two mite species did differ in their seasonality, but a stro

Larval Arrenurus mites establish a phoretic association with pupal mosquitoes and wait for emergence of the adult upon which they feed. In the laboratory, four Aedes spp. were given equivalent exposure to larvae of Arrenurus angustilimbatus Mullen an

In this study, the spatial and temporal patterns of emergence of mosquitoes in a temporary autumnal pool were related to parasitism by larvae of the mites Arrenurus kenki Marshall and Arrenurus angustilimbatus Mullen. There was differential mite para
