"The Winter Tick Observation Network aims to map where, when, and on which host animals winter ticks are found throughout their range in North America. The project encourages the public to report sightings of winter tick (Dermacentor albipictus) including off and on host. Off host includes ticks and larvae visible on vegetation (grass, shrubs) from August to November. On host includes patchy hair on moose, elk, caribou, deer in March to May that might be due to winter tick infestation."
