…Acarid mites generally consist of five stages: eggs, juvenile mites, pre-nymphs, post-nymphs, and parent mites. However, when the environment deteriorates, the pre-nymphs turn into migratory mites called hypopus, and when the environment improves again, some turn into post-nymphs. If the environmental conditions are good, it takes about two weeks for eggs to develop into parent mites. … From [Mite (蜱, 蟎, 壁蝨)] …The number of days it takes for eggs to develop into adults varies greatly depending on the species, but under good conditions it takes about 10 days for dust mites, 2 weeks for house mites, about a month for ticks, and about 3 months for chiggers and oribatid mites. Some dust mites develop a special stage called the hypopus (migratory nymph) during development, which is highly resistant to low temperatures, high temperatures, dryness, and chemicals. *Some of the terminology that mentions "hypopus" is listed below.
