Trombicula autumnalis are [[Non-Burrowing Mites|surface mites]]. They cause [[Trombiculidiasis|parasitic skin infestation]] and will parasitise any animal, including humans as they are non-species specific. The mite numbers are highest in late summer in temperate climates and are therefore constant all year in tropical regions. | Trombicula autumnalis are [[Non-Burrowing Mites|surface mites]].
