Several of the Indian Milkweed Plants growing wild in Elyria Canyon Park have serious Milkweed Aphid infestations, and one especially hard hit group of plants is also covered in black Sooty Mold.  See the University of California Agriculture and Natural Resourceswebsite for more information on Sooty Mold.

Convergent Lady Beetles, Hippodamia convergens,  have begun to feed off of the Milkweed Aphids, though it seems there are far too many Aphids for the few Lady Beetles that were observed.  Learn how to identify the Convergent Lady Beetle on BugGuide and read more about the benefits of the native Convergent Lady Beetle on the San Francisco State University Department of Geographywebsite.
