Life cycle and appearance of Cyclamen mite The life cycle of the cyclamen mite ( Phytonemus pallidus ) has the following stages:

In gerbera, the larva of the American serpentine [...] indirectly. The most direct damage is caused by the larvae mining the leaf tissue, leading to desiccation, premature leaf-fall and cosmetic damage. In tropical
