Fourth instar(?) caterpillar on Asclepias fascicularis. We planted 21 four-five inch seedlings in our native section of our garden of this type of milkweed and hope it can support the two caterpillars I've seen.

Found a monarch butterfly on my milkweed (possibly offspring from my last years caterpillars) next to the biggest caterpillar on my milkweed, (possibly it's baby) and my dad took this picture of it. I found 5 caterpillars on the milkweed in my backyard.

"Found this seed pod on my milkweed today. This afternoon, there was a soft offshore breeze that was just about ready to loft all these seeds into the air.

"After I took the photo, I snipped off the seed pod and put it into a small paper bag. That is where I keep my seed collection."

"January 6 2015. I found a large caterpillar on a milkweed in my front yard.

"January 18th. Cat attempted to attach the chrysalis to a stucco wall near the plant. I found the chrysalis on the ground, with bits of decomposed granite attached to it. It also had bits of the caterpillar shell at the top, and that was easily removed. Other than being slightly misshapen on the side that was resting on the ground, the chrysalis looked OK.
I brought it into the house, and initially tried to embed the cremaster into the cotton end of a swab. I read that it needs to hang to develop properly.

"January 19th. The next day, I secured the cremaster to the swab with some cotton thread. It hung from the inside edge of a plastic container padded with facial tissue until January 30th.

"January 30th. I was startled to find a butterfly on the edge of the container, just starting to exercise his wings. I quickly covered the butterfly and the container with a tissue, and took him outside, placing him next to a milk weed plant. He did fine!"

"I planted three milkweeds in my yard in August 2014 under west facing windows.

"January 6 2015, I noticed this large caterpillar on the milkweed.

"January 13th. Formed a "j", then a chrysalis underneath a windowsill close to the plant. The second chrysalis photo was taken a few hours before enclosure.

"February 3rd. He successfully enclosed in the afternoon. It was very fast. One photo was taken right after he climbed out; he was hanging on to his chrysalis shell and waiting for his wings to dry.

"February 5th. He found two companion butterflies and was spending time in my yard."

Description

"Late last summer I discovered after recently moving to this house that NOTHING would really grow on on the "hot" side of my yard without tons of care and water. I typically avoid annuals and water hogging plants and prefer perennials, since we have drought conditions here.

"That's how I came to purchase an Asclepias tuberosa for this location. Drought resistant and had amazing flowers...

"About two weeks ago, I noticed a monarch all around this particular plant on one of the first really warm, sunny days. Knowing their history and that this milkweed had a couple of flowers blooming on it, I didn't really consider it a huge deal. About a week and a half after that, the plant was really dying off and I checked it to see what was the matter. I quickly found the cause. (see shots 1, 2, 3)

"These tiny caterpillars of course quickly began to grow and devoured that entire plant.

"Seeing they were hungry and getting larger, we purchased a couple local milkweed plants that were not treated with pesticides at a local nursery. These were about 2.5' high with larger leaves and multiple stems. I set them in a pot near the devoured plant and they soon got the idea an jumped on. After about 2 days they ate the entire lot, stems and all. Much bigger now, there were about 25 survivors all in instar 4 or 5. That's when I called you, since I wasn't sure what to do with them...
(see shots 4, 5, 6, 7, 8)

"They've since wandered off and into the surrounding trees to hopefully make it to pupation... :)"

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.
