Photo: Diane Edwardson, October 1, 2009. Ladybugs appear to herd yellow aphids on native Milkweed. (Click on photo to enlarge.)I noticed lots of tiny yellow bugs on many of the Milkweed (Asclepias fascicularis) plants on the 18-Acre Elysian Park Parcel (between Riverside Drive and Landa). Each plant seemed to have one or two Ladybugs methodically going up and down every leaf as if they were keeping the Oleander Aphids (Aphis nerii) confined to certain leaves.
There are hundreds of species of Ladybugs within the Coccinellidae family. Learn more: Bug Guide.
