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.

Hump-backed Fly

A tiny scuttle fly with a distinctly humped thorax that breeds in an extraordinary range of organic matter. It is forensically important especially in enclosed burial sites.

💡
