Two-Spotted Spider Mite (Tetranychus urticae)

These microscopic arachnids thrive in the warm, dry conditions often experienced by Viola cornuta. They pierce the leaf cells to suck out nutrients, leaving behind characteristic fine silk webbing and stippled yellow spots on the foliage.

While not a web-producing pest, rapid fluctuations in soil moisture can cause cells to burst, sometimes creating a fine, white, crusty residue on leaf margins that can be mistaken for webbing.

Common
