We have studied the invasion, behavior, and ecology of this parasitic fly, and in this paper briefly review the effect of climate on the distribution of deer keds and our recent findings from host-choice experiments. The rapid increase of the deer ked is correlated with high moose densities in Finland. We propose that the availability of suitable hosts, not climate, is the primary factor affecting its northward range expansion. Our host-choice experiments indicated that deer keds are attracted by movement and large, dark objects. Our results suggest that this parasite may continue to spread northwards in the near future, and that its potential impact on cervids and human health warrants attention.}, journal={Alces: A Journal Devoted to the Biology and Management of Moose}, author={Kaitala, Arja and Kortet, Raine and Härkönen, Sauli and Laaksonen, Sauli and Härkönen, Laura and Kaunisto, Sirpa and Ylönen, Hannu}, year={2009}, month={Jan.}, pages={85–88} }
