**Mange mites**
61
Ventral side of Psoroptes male. Males are less common than females. Their ambulacrum is similar to the female’s one. They have two circular suckers close to the anal pore on the rear end.

**Mange mites**
63
Larva of Psoroptes has only six legs. (The fourth pair of legs is missing on them.) They are much smaller than the members of subsequent stages
**Mange mites**
64
Chorioptes bovis female. The species is similar to the Psoroptes mites but its funnel-shaped ambulacrums are short because they short stalked.
**Mange mites**
65
Chorioptes bovis male. Last pair of legs in males of non-burrowing mites is always longer than the same legs of females.
**Mange mites**
66
Frontal pairs of legs of Chorioptes mite. Funnel-shaped suckers of ambulacrums on the tarsal tips of front legs can be seen well.
**Mange mites**
67
Otodectes cynotis male. Funnel-shaped suckers of ambulacrums on tips of frontal pairs of legs are precisely in case of Chorioptes.
**Mange mites**
68
Otodectes cynotis female. Her ambulacrums are similar to the males’ ones. Hind legs are so small that sometimes avoid recognition. This species is almost indistinguishable from species of Chorioptes genus by morphology but its habitat and host precisely indicate their real identity. They much more often can be found on cats than on dogs.
**Mange mites**
69
A male feather mite from a zoo bird. Body of every species is elongated in order to avoid the effect of preening. Harmless mites in quill and shaft of feathers or among the barbs are very common in wild birds. They feed on keratin. Sometimes the barbs brake in consequence of chewing and the vane of feather becomes porous.
**Mange mites**
70

**Harvest mites or chiggers**
87
Red pigment of chigger larva partly leaked out of the body during the process of preservation.
**Harvest mites or chiggers**
88
All dark coloured red mites are nymph or adult because larvae do not feed. Their body is filled with blood. They feed several times in each stage
**Poultry red mites**
89
Pedipalps of red mites are slimmer than the pedipalps of the ticks. Their long and thin fibreshaped hypostome and chelicerae are seldom seen.
**Poultry red mites**
90
Two hooked claws on the tip of long legs are the most striking characteristics of the **Argas larva.**
Metastigmatid mites: soft and hard ticks
91
Club shaped pedipalps and shorter legs are the main characteristics for the larva of **ixodid ticks.**
