The larva is an active, feeding instar invariably present in mite life cycles. After eclosion, larvae shed both prelarval skin and chorion. In most bee-associated mites, this is the first active stage. It is usually a weak, miniature stage, but in some groups, larvae are aggressive parasites (Parasitengona) or predators (family Cheyletidae).
Mites which colonize human skin are the cause of several types of itchy skin rashes, such as gamasoidosis, [51] rodent mite dermatitis, [52] grain itch, [53] grocer's itch, [53] and scabies; Sarcoptes scabiei is a parasitic mite responsible for scabies, which is one of the three most common skin disorders in children.

These water mite larvae are also hosts of Callicorixa, Corixa, Cymatia and Sigara species, although Sigara falleni has been described as "immune" to these mites, and Cymatia coleoptrata and Sigara striata also gain this "immunity" after a few years of interaction.
Erythraeidae is a family of mites belonging to the Trombidiformes. [2] Larval forms of these mites are parasitic on various other arthropods, for example harvestmen, but the adults are free-living predators. These oval mites are rather large, usually reddish coloured and densely hairy.
Larvae of Parasitengona are usually ectoparasites of arthropods, and they make up most of the red mites that can be found attached to arthropods. Some (e.g. chiggers) use vertebrates as hosts instead. There are also species with free-living larvae. [7] [8] Water mite (Hydrachnidia) Erythraeidae (Erythraeoidea) larva attached to Opiliones leg
Larva: Six-legged, hatching from the egg and cutting through the skin to dig new burrows. Nymph: Molts from the larva to become a first- or second-stage nymph. Adult: Round, sac-like, and eyeless. The complete life cycle takes about 2–3 weeks. Adult female mites lay 2–3 eggs per day within the skin’s outermost layer, the stratum corneum.
This species is one of the largest mites in northern temperate zones, with a body length of about 4 mm (just over 1 ⁄ 8 inch). The soft, brightly red body is covered with fine hairs, giving it a velvety appearance. The small eyes are located on stalks. They have scissor-like chelicerae and their pedipalps are used as touch organs.
Eylais mite larvae are ectoparasites of diving beetles . They attach mainly to the ventral side of the hindwings underneath the elytra and may be feeding on hemolymph from here. [2] The smallest (and hence youngest) larvae occur on beetles in early spring, suggesting that some Eylias overwinter on their hosts. The larvae grow rapidly and reach ...
