The deuteronymph, which is the second stage of the life cycle, actively parasitizes and is similar to an adult mite in size and appearance.

[9] It has been demonstrated that Spinturnix mites end their reproduction and metamorphosis in winter, when their host species go into hibernation cycles.

The life cycle of these mites is extremely shortened, which contributes to the instinct to preserve the offspring.

These preferences demonstrate the Spinturnix mite's ability to detect the host that they find to be the most beneficial to their survival.

[12] Spinturnix mites have a strong influence on the health and fitness of their host species of bats.

It has been demonstrated that pregnant or lactating bats have experienced increased oxygen consumption and weight loss due to Spinturnix infestations.
