The Blacklegged Tick, also known as the Deer Tick (Ixodes scapularis), is a small arachnid commonly found in wooded and grassy areas. It is known for its role in transmitting diseases such as Lyme disease and Anaplasmosis to humans and animals. Adult ticks are typically active in the fall and spring, while nymphs are most active in the late spring and summer. These ticks are characterized by their dark brown to black coloration and can be as small as a pinhead. They attach to hosts, including mammals and birds, to feed on blood. Proper precautions, such as wearing protective clothing and using insect repellent, can help reduce the risk of tick bites.
