Aphid Infestation

Aphids are small, soft-bodied insects that pierce the succulent tissues of Euphorbia bupleurifolia to suck sap. They excrete a sugary substance known as honeydew, which creates the sticky residue on leaf surfaces.

Scale Insects

Scale insects attach themselves to the stems or leaves of the spurge and feed on plant fluids. Like aphids, they produce honeydew as a byproduct of feeding, which coats the foliage in a sticky film.

Common

Mealybug Infestation

Mealybugs are related to aphids and secrete honeydew while feeding on the plant's nutrients. They often hide in the crevices of the Euphorbia's foliage, leaving behind a sticky residue.

Common
