Milkweed Aphid

Aphis nerii


Tiny little yellow bugs that suck the life out of milkweed, oleander and a few other plants. This is a non-native invasive species.


Tropical and Mediterranean climates. San Diego is a Mediterranean climate zone, so they flourish here.


This is interesting! "Female aphids lay live young (nymphs), a process known as viviparity. Female aphids reproduce by parthenogenesis, males have never been observed in the wild but have been produced under laboratory conditions" (Wikipedia)

Great shot and write-up Ava. Weird. Like the most dominant male Clownfish changing sex and taking the place of the matriarch of the group when she dies. Very strange.
