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.
Arctic Psyllid
A tiny, winged sap-sucking insect that feeds on willow in Arctic and subarctic regions. Adults are brownish with transparent wings and can jump powerfully using enlarged hind legs. Nymphs produce waxy secretions.
Did You Know?
Psyllids are sometimes called jumping plant lice because they can leap more than 50 times their own body length to escape danger.
