"I found this guy in the middle of the path at the La Brea Tar Pits, near the Page Museum. It wasn't flying and seemed to be stumbling quite a bit, so I scooped him up and placed him on the nearest flowering plant I could find before a group of joggers came by.

This was at 8:00 am on Jan. 10, 2015. The weather was pretty cool and it was just starting to rain." - Ranjit

"These pictures were taken from Oct. 25,2014 to Dec. 18, 2014. As I observed, it takes more than two weeks for the caterpillar to reach its maturity, and another two weeks before it came from its cocoon...and hang for 2 hours to dry out, and gain its strength to fly." - Cesar

"I live in Pasadena and planted 3 milkweed (including 1 asclepias physocarpa) in September. Within 2 weeks, I observed several Monarchs and soon after a continuous cycle of caterpillars. I'm so excited to do my small part to restoring the Monarch population and am planning on planting more milkweed." - Nancy Shiffman

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.
