Chigger (Berry Bug or Harvest Mite)

Low, damp vegetation, gardens, grassy fields, and wooded areas with thick undergrowth.

The larval stage feeds on skin cells and digestive enzymes of host animals; adults feed on plant material and small insects.

Larvae attach to hosts in passing; they do not burrow but pierce the skin and inject enzymes to liquify cells. After feeding for a few days, they drop off to molt into nymphs.

Their bites cause intense itching and red welts due to an allergic reaction to their saliva. They do not feed on blood or spread disease in most regions, but are significant nuisance pests.
