What type of parasite is a chigger?

A chigger is classified as an arachnid ectoparasite. This categorization stems from its biological classification; chiggers belong to the mite family, specifically in the subclass Acari, which includes both ticks and mites. As ectoparasites, chiggers attach to the skin of a host (often mammals) to feed on tissue fluids, such as lymph.

Understanding the role of chiggers in their ecological niche is essential for managing their impact effectively. They are known for causing intense itching and irritation due to the enzymes they release while feeding, which can lead to secondary infections if not addressed. Moreover, knowing their classification helps in recognizing their life cycle, habitat preferences, and methods of control.

In contrast, the other choices refer to different types of parasites that do not fit the classification of chiggers. For example, insects are separate from arachnids as they have a more complex body structure and developmental stages. Helminths, which include worms like tapeworms and flukes, and protozoans, single-celled organisms that can also be parasitic, represent entirely different groups and life processes that do not include chiggers. Thus, understanding the specific classification of chiggers reinforces the right identification of their nature as
