Oleander Aphids Aphis nerii
July 3, 2007
I found this brown Syrphid (fly) larva munching on these aphids on my milkweed leaves. These aphids are European transplants. The predator doesn't seem to be deterred by the bad-tasting toxin taken up by the aphids as they eat the sap of the milkweed. They use the bright orange coloration to deter predators.
