What's eating my bicalcarata pitcher plant?
Scale insects
Signs: Small brown or tan bumps on stems and leaf undersides; honeydew deposits lead to sooty mould on pitchers.
Control: Scrape off manually, then wipe with a cotton swab dipped in rubbing alcohol; treat with horticultural oil spray. Separate from other plants immediately.
Mealybugs
Signs: White cottony clusters in leaf axils and near the pitcher lid; sap feeding weakens pitcher production.
