What's eating my bucephalandra black pearl?

Bucephalandra Black Pearl is a slow-growing aquatic aroid kept submerged or emersed indoors. Its toughest pests are spider mites and mealybugs on emersed leaves. Fully submerged plants are largely pest-free, but emerged growth in humid terrariums can attract fungus gnats if substrate stays waterlogged.

Fine webbing and pale stippling on emersed leaves; leaves may yellow and crisp at edges in low humidity. Raise humidity, rinse foliage with water, apply neem oil or insecticidal soap to affected leaves; submerged portions need no treatment.

White cottony clusters at leaf axils and stem joints on emersed growth; sticky honeydew residue. Dab colonies with a cotton swab dipped in 70% isopropyl alcohol; follow up with diluted neem oil spray on emersed portions.

Larvae damage fine roots in waterlogged substrate; adults are a nuisance around the tank. Allow substrate surface to dry between waterings; use yellow sticky traps for adults; add a layer of coarse sand over the soil surface.
