Likely chigger (harvest mite larva)

Leaf litter, grassy vegetation, soil, and woodland edges; larvae attach temporarily to animals and people.

Larvae feed on liquefied skin tissue and lymph after injecting digestive enzymes; adults and nymphs eat small arthropods and organic matter.

Six-legged larvae climb vegetation and attach to passing hosts, commonly causing intensely itchy bites for several days. They do not burrow into skin or remain attached long-term.

Can cause itchy dermatitis; some Asian species transmit scrub typhus, but this is not typical of North American chiggers. Adults and nymphs help regulate small soil-arthropod populations.
