Citrus Spittlebug

A small oval-shaped spittlebug with dark brown and cream banding. Nymphs produce frothy spittle masses on pecan, citrus, and other trees throughout the southeastern United States.

💡

Did You Know?

Spittle masses produced by the nymphs can be so abundant on pecan trees that they rain down on people walking beneath, giving the impression of a light drizzle.

Oleander Aphid

A bright yellow aphid with black cornicles and legs that feeds on oleander, milkweed, and other plants containing toxic cardiac glycosides. It sequesters these toxins for its own defense.

💡

Did You Know?

Its bright yellow color serves as aposematic warning coloration because it sequesters cardiac glycosides from its host plants, making it toxic to most predators.
