Birth control


I just found aphids on one of my plants. The easiest way to get rid of these tiny dudes is to get ladybugs, who eat them. Since my plant is inside I've been looking into other ways to deal with them, working off the assumption that my housemates aren't that down with a beatle infestation in the kitchen.

I don't know yet what I'm going to do with the aphids, but I did find out that ants love this sweet juice that aphids squirt out. They love it so much they farm aphids and protect them from nasty ladybugs and slurp on their precious.

The other important thing about aphids is half the time they breed sexually, but the other half, the females just make new aphids by themselves. It gets super crazy because sometimes a female aphid will have an emryonic female aphid inside of her, who also has an embryonic aphid inside of her. It's called telescoping generations.

My other favorite animal that breeds asexually is the bdelloid rotifer. There hasn't been a boy bdelloid rotifer in like 40 million years.

Update: In case anyone else has an aphid problem, Dr. Bronners mixed with water seems to kill them.
