There are other red mites, also quite abundant this time of year, that crawl in to buildings. Their body shape is not like that on Bryobia mites and the relative leg lengths aren’t what you see in this in so far as the hind 6 are subequal and have the first pair very long. The red trombidioid or erythraeoid (often called velvet) mites have subequal legs and the tarsi are slightly enlarged. Sometimes the legs can be many times the body length, too. Some are pollen feeders and you normally see the nymphs and adults crawling about. These have 8 legs. Larvae are parasitic on other arthropods and have 6 legs and are not as velvety as nymphs and adults.

The mite is reminiscent of the clover mite, Bryobia praetiosa. There are yet other mites that are fairly consistent in form, but this one is particularly abundant, especially in warmer months. They wander into dwellings though impressively tiny gaps in the building envelope. Richard J.
