What's eating my colocasia 'pink china'?

Colocasia 'Pink China' grown outdoors attracts aphids, spider mites, and caterpillars, while slugs and snails shred the large tropical leaves at ground level. Deer and rabbits may browse the foliage in garden settings. Indoors it is most troubled by spider mites in dry conditions. Regular inspection and prompt treatment keep it healthy.

Fine webbing on leaf undersides; pale, stippled or bronzed foliage Raise humidity, rinse leaves with water, apply insecticidal soap or neem oil spray weekly until clear

Clusters of soft insects on new growth; sticky honeydew and distorted, curling leaves Knock off with a strong water jet; treat with insecticidal soap or neem oil; introduce ladybirds outdoors

Irregular ragged holes in large leaves, especially near the base and at night Remove by hand at dusk, use iron-phosphate slug pellets around the base, and keep mulch away from stems

Large irregular holes or skeletonized sections on the broad leaves Hand-pick eggs and larvae; apply Bacillus thuringiensis (Bt) spray to foliage for heavy infestations
