Definition
Noun: 1. A larval mite that sucks the blood of vertebrates, including humans, causing intense irritation: This term refers specifically to the parasitic larval stage of certain mites, particularly those of the family Trombiculidae. These tiny, often red-colored larvae attach to the skin to feed on tissue fluids, resulting in itchy, red welts.
Usage Examples
- Noun:
- After hiking through the tall grass, I found a redbug attached to my ankle.
- The intense itching is a classic symptom of a redbug bite.
- Wearing long sleeves and pants can help prevent redbug infestations.
Advanced Usage
- The term "redbug" is often used interchangeably with "chigger" in common American English, though "chigger" is more widely recognized. In strict entomological terms, "redbug" can sometimes refer more specifically to certain regional species.
- The irritation is not from a bite in the traditional sense, but from the larva's feeding process and its digestive enzymes, which cause a reaction in the skin.
