- Western Europe to Eastern Asia.
- The mite has not been found in the Nearctic region, and only isolated populations have been observed in the Palaearctic region.
- Not seen in Australia.
- There are several hundred different species of Trombiculidae (chigger) mites recognized across the world.
- Only a small number of Trombiculidae mites cause disease in man and animals.
- Only the larval stages are parasitic to mammals. The remainder of the life cycle is completed in the environment with the nymphal and adult stages feeding on insect and vegetable matter.
- The larvae feed for 2-10 days using their chelicerae to inject lytic enzymes into the upper layers of the skin and to ingest the digested cells.
- N . autumnalis is the most familiar pathogenic Trombiculidae mite in Europe.
- The animals most frequently infested are small rodents and dogs.
- Mite larvae of the species N . autumnalis cause autumnal erythema (trombiculiasis or trombidiosis), a short lasting pruritic dermatitis in humans. This occurs in people who visit meadows or woods during the summer or autumn. Transmission from rabbits to humans does not appear to have been recorded.
