Deer (Blacklegged) Tick

(Ixodes scapularis)

The Blacklegged Tick is also known as the Deer Tick. All three active stages of the Blacklegged tick will feed on a variety of hosts including people. After the eggs hatch in the spring or summer, the very tiny larvae feed primarily on white-footed mice or other small mammals or birds. The following spring or early summer, the larvae molt into pinhead-sized, brown nymphs that will feed on mice, larger warm-blooded animals and people. In the fall, they molt into adults that feed primarily on deer, with the females laying eggs the following spring. 

Deer (Blacklegged) Tick

Adults are reddish-brown and about 1/8-inch long (or about one-half the size of the more familiar female American Dog Tick). These ticks are found in wooded areas along trails. The larvae and nymphs are active in the spring and summer; adults may be active in both the spring and fall. The Blacklegged tick can transmit Lyme disease and ehrlichiosis to humans.
