Dermacentor reticulatus, also known as the ornate cow tick, is a tick species known for its intricately patterned shield. It inhabits grasslands and forests across Europe and Asia. This tick is a vector for pathogens like Babesia canis, affecting both domestic and wild animals.

Dermacentor reticulatus, commonly known as the ornate cow tick, is predominantly found in the Palearctic region, which includes parts of Europe and Asia. Its geographical distribution spans across several European countries such as France, Germany, Poland, and the United Kingdom, extending into parts of Western Asia.

Dermacentor reticulatus typically inhabits temperate climates with moderate to high humidity. It is commonly found in a variety of environments including grasslands, forests, and agricultural areas. The species prefers regions with dense vegetation which provides adequate cover and humidity necessary for its survival.

As an ectoparasite, Dermacentor reticulatus primarily feeds on the blood of large mammals, including livestock and wildlife, which makes it an important vector for various pathogens. The tick's ecological niche involves parasitizing hosts found within its native habitat, contributing to the transmission of diseases such as Babesiosis among animals.
