Notable Species

Pachylaelaps squamosus: Often studied for its predatory habits.
Pachylaelaps stercoralis: Known for inhabiting animal dung.

Conservation

While there's no immediate conservation concern for the family as a whole, habitat preservation is essential to maintain the ecological roles these mites play.

Significance to Humans

Pachylaelapids contribute to pest control and nutrient cycling in various ecosystems. Their predatory nature helps manage populations of other small arthropods that might otherwise become pests.

Fun Facts

Some species are used in biological control programs due to their predatory nature.
Pachylaelapids can be challenging to study due to their small size and cryptic habitats.
Despite their minute size, they have complex mating behaviors.
