Two-Spotted Spider Mite Infestation

Spider mites thrive in the warm, dry environments often experienced by Calla Lilies, using fine silk to create webs around the foliage and flower spathes. These tiny arachnids pierce plant cells to feed, leading to stippling and eventual yellowing of the leaves.

Very Common
