Dermacentor albipictus (Packard, 1869)

Dermacentor albipictus, the winter tick, is a species of hard tick that is an external parasite of moose (Alces alces) in North America. Heavy infestations of tens of thousands of ticks have been seen on single moose, and can lead to the death of the animal.

There is evidence that the winter tick may be responsible for a steep decline in the Eastern moose population throughout the southern half of their range.
