Backswimmer

An aquatic bug that swims upside down just beneath the water surface, using its long hind legs as oars. Its back is keeled like a boat hull and pale-colored for camouflage when viewed from below.

💡

Did You Know?

Backswimmers swim inverted with their pale backs facing downward, providing counter-shading camouflage against the bright sky when predators look up from below.

Aphid

Tiny sap-sucking insects with extraordinary reproduction. Can reproduce without mating (parthenogenesis) and give birth to live young that are already pregnant, telescoping generations.

💡

Did You Know?

Aphids can telescope generations — a female can contain a developing daughter, who already has a developing granddaughter inside her, all without mating.
