Two-Spotted Spider Mites (Tetranychus urticae)

The presence of fine webbing is a classic sign of a spider mite infestation, which thrives in the warm, dry conditions often experienced by pansies and violets. These mites pierce the leaf cells to feed, leading to stippling and eventual leaf senescence.

Very Common

How to confirm: Hold a white piece of paper under a leaf and tap the leaf sharply to see if tiny crawling dots fall onto the paper.

Edermine Mites (Tarsonemidae)

While less common than spider mites, these microscopic mites can cause webbing and distortion in Viola species. They often attack the tender new growth and flower buds of pansies/violets.

Common

1 Isolate the plant immediately to prevent the mites from spreading to other indoor greenery.

2 Apply an organic miticide spray to the plant, ensuring you coat the undersides of leaves and tender new growth where mites hide.

3 Gently wipe the leaves with a damp cloth to physically remove webbing and any remaining mite populations.

warning

High Humidity with Low Air Circulation

In some cases, extremely high humidity combined with stagnant air can cause fine, fungal hyphae to appear web-like on the surface of Viola leaves. This is often accompanied by moisture droplets or a damp feel on the foliage.

Common

How to confirm: Check if the webbing feels 'sticky' or if there are small dark fungal spots (Botrytis) appearing alongside the webs.

1 Increase air circulation around the plant by using a small fan to prevent stagnant, humid air from settling on the foliage.

2 Apply a fungicide to treat the web-like fungal hyphae and protect the leaves from further moisture-related decay.
