They're all female Blacklegged (Deer) ticks
Blacklegged ticks (a.k.a Deer ticks) take 2 years to
complete their life cycle and are found predominately in deciduous
forest. Their distribution relies greatly on the distribution of its
reproductive host, white-tailed deer. Both nymph and adult stages
transmit diseases such as Lyme disease, Babesiosis, and Anaplasmosis.
They're all nymphal Blacklegged (Deer) ticks
Blacklegged Nymphs are active May-August, and are most
commonly found in moist leaf litter in wooded areas, or at the edge of
wooded areas. The eight-legged, pin-head sized nymph typically attaches
to smaller mammals such as mice, voles, and chipmunks, requiring 3-4
days to fully engorge. Nymphs also readily attach to and blood feed on
humans, cats and dogs. Once fed, they drop off into rodent burrows or
leaf litter in animal bedding areas where they molt and emerge as adults
in the fall.
They're all female American dog ticks
American Dog ticks are found predominantly in areas with
little or no tree cover, such as grassy fields and scrubland, as well as
along walkways and trails. They feed on a variety of hosts, ranging in
size from mice to deer, and nymphs and adults can transmit diseases such
as Rocky Mountain Spotted Fever and Tularemia. American dog ticks can
survive for up to 2 years at any given stage if no host is found.
Females can be identified by their large off-white scutum against a dark
They're all female Lone Star ticks
Lone Star ticks are found mostly in woodlands with dense
undergrowth and around animal resting areas. The larvae do not carry
disease, but the nymphal and adult stages can transmit the pathogens
causing Monocytic Ehrlichiosis, Rocky Mountain Spotted Fever and 'Stari'
borreliosis. Lone Star ticks are notorious pests, and all stages are
aggressive human biters.
They're all Lone Star nymphs
Lone Star nymphs are active May- early August, and can be
found questing for deer, coyotes, raccoons, squirrels, turkeys and some
birds as well as cats, dogs and humans.
