Description

"I started planting milkweed in my yard for the monarchs about two years ago and have become a Waystation. The butterflies and flocks of goldfinches loved the verbena bonarensis this year. I collect the eggs and bring them inside, feed the caterpillars and finally release the butterflies. I probably have released about 350 a season/year. I have about five varieties of milkweed. I have noticed that there have been more butterflies and eggs in the yard for the past two days--maybe starting to return?. The neighbor around the corner has about 6 or 7 plants." - Susan Whisnant

"Here are the milkweeds. We only have three. The one in the first picture we just bought a few days ago. It's already loaded with at least 10 eggs.

The last picture was a full size plant that got absolutely devoured last week." - Teri Adamson

About

The Natural History Museum of Los Angeles County (NHM) has begun studying our local urban environment to better understand the biodiversity that lives in the Greater Los Angeles Area. Part of this study includes knowing where local populations of monarch butterflies and milkweed plants are found.
