Notes

These mites are deutonymphs (second instar nymphs) of some species of the family Acaridae. The deutonymph in these species is a non-feeding stage that functions only for dispersal. This morph is called a hypopus (plural hypopodes) and will be attached to the spider by a ventral sucker plate. They are not parasites.
