Explanation:

Understanding Chiggers

Chiggers are the larval stage of certain mite species, notably from the family Trombiculidae, known for their biting habits. Here are some key points:

  • Chiggers are non-human biting mites: They specifically feed on skin cells of humans and animals.
  • Chiggers are the source of mite allergens: Their bites can lead to allergic reactions due to the enzymes they inject to digest skin cells.
  • Chiggers are the larvae of the harvest mites: This is correct as harvest mites belong to the Trombiculidae family.

However, it's important to note:

  • Chiggers are not the only lifestage of Trombiculidae that feed on animals; only the larvae do.
  • Chiggers are not characterized as human parasitic mites in the same way as some other mites like scabies mites.

In summary, chiggers are an important aspect of ecology, as they have a role in both biodiversity and human health concerns.
