What's eating my hoya pubicalyx 'royal hawaiian purple'?

Hoya pubicalyx 'Royal Hawaiian Purple' faces the same pest pressures as other Hoya pubicalyx cultivars. Mealybugs are the most frequent problem, hiding at nodes and in leaf axils along the long twining stems. Spider mites, scale insects, and aphids on developing flower buds are also common indoor and light-outdoor threats.

White waxy tufts at nodes, leaf axils, and inside flower clusters; honeydew deposits lead to black sooty mold Dab with 70% isopropyl alcohol on a cotton swab; spray with neem oil; repeat weekly; check flower clusters carefully

Bronze-yellow stippling on the dark glossy leaves; fine webbing visible in dry indoor conditions Raise humidity; shower the plant to knock off mites; apply insecticidal soap or neem oil every 5–7 days for 3 weeks

Small, hard brown bumps on stems and the underside of leaves; sticky honeydew below the plant Pick off manually or scrape with a soft brush; wipe with alcohol; follow with horticultural oil every 2 weeks

Clusters of soft insects on new shoot tips and near developing flower spikes; distorted buds and sticky residue Rinse off with water; apply insecticidal soap spray; inspect new growth and flower spikes regularly through spring
