Aphids

PINK aphids! Found with some green aphids on the same plant.

Aphids are amazing insects. They can reproduce either sexually or asexually (more common) and either give live birth or lay eggs. They usually reproduce by parthenogenesis, with adult females birthing offspring genetically identical to themselves. (So, most aphids are female.) When food is scarce, mothers give birth to winged daughters, who can fly to a new location and start new populations where there is less competition for food. They sometimes even reproduce telescopically, with a mother aphid generating a clone daughter who is already pregnant with her own daughter.

These pink aphids have an even wilder adaptation (if I understand correctly; maybe they don't count as "red"?). From Wikipedia: "Some species of aphids have acquired the ability to synthesise red carotenoids, by horizontal gene transfer from fungi. This allows otherwise green aphids to be coloured red... A team of researchers at the Sophia Agrobiotech Institute in Sophia Antipolis in France, have suggested that carotenoids may absorb solar energy and convert it to ATP. This is the first example of photoheterotrophy in animals... It is unclear why aphids should find it necessary to develop this source of energy when their diet provides them with an excess of sugars." ANIMALS that get energy from the sun!

Yeah, they suck sap from plant stems and are a major agricultural pest. But aphids are still amazing creatures.
