Adult-stage female Dermacentor variabilis (a.k.a. American Dog tick) Growth Comparison

Adult males and females are active April- early August, and are mostly found questing in tall grass and low lying brush and twigs. They feed on medium-sized wildlife hosts, including raccoons, skunks, opossums and coyotes, as well as domestic dogs, cats and man. Adult American dog ticks commonly attack humans. Male ticks blood feed briefly but do not become distended with blood. Once finished feeding, males mate with the female while she feeds, which can take one week or more. Once replete, female dog ticks detach from their host and drop into the leaf litter, where they can lay over 4,000 eggs before dying.
