Monarch Butterfly Sanctuary


My husband and I escaped town on the 26th and headed down the coast with some friends to visit Hearst's Castle. We had booked the night tour and missed it because of a slow waiter, but the friendly state park ranger on duty took pity on us and switched our tickets for a tour the next morning. The tour was interesting and we had a lovely time driving up the coast through Big Sur, including a stop to see the elephant seals covering the beach at Piedras Blancas. But the highlight of the day for me came at the very last stop when we visited the Pacific Grove Monarch Sanctuary.

The volunteer manning the telescopes in the grove told us they estimated that 19,000 Monarchs were spending the winter in the grove. These butterflies may have flown as far as 2,000 miles to reach the winter sanctuary. Most amazing to me is that they have never been to the sanctuary before, they hatched and became full grown (but not sexually mature) somewhere in the Pacific Northwest. In February, longer and warmer days will trigger the butterflies to become fully mature and they will start the northward migration, mating and laying eggs along the way. It will take 4 or 5 generations to reach their full northern range because the northward migrating butterflies have a much shorter lifespan than the southward migrating generation.

My camera is not good enough to get a good shot of the monarchs hanging in the trees but I've posted a couple to give an idea of what the clusters look like. They hang in masses in the trees to conserve warmth.

In the photo above you can see a mass of butterflies to the right of center between the large tree trunk on the right and and the short thin trunk just to the left. Barely discernible flecks of orange are monarchs that are basking in the sun. When the temperature gets above 55F they are able to fly about in search of food. When I was there, it was cold in the shade but warm enough in sunny patches for the butterflies to be active.

The photo below shows what looks to be dead leaves, but that's a pine tree, and we all know that pine trees have needles, not leaves. All those leafy looking things are monarchs.

So, now I need to get away from the computer and get outside while the sun is shining (yeah!) and get some cleanup done in the garden.

  1. Wow,that had to have been a sight! I'm so jealous of your weather. The weather here in Texas has been quite contrary and colder than usual. I hope you have enjoyed your holidays.

  2. Hi Ang, the holidays were good, not necessarily the weather - cold, wet, hail even. It cleared up on the 26th so the post holiday trip was at least sunny.

  4. They're beautiful. I remember seeing them when I was really young in the garden in our old house! Aaahhh! It's been more than 20 years now and I suddenly remember it after seeing your post. Thank you!

  5. What an amazing place! It's cold here too - the monarchs wouldn't like it. Happy New Year!

  6. Susan, Chandramouli, chaiselongue - it is wonderful to see all those butterflies in one place. That's the first time I've seen it and I've lived in California my entire life. Can't believe it took me so long to get around to it.

  7. All I can say is wow, so cool to be so close to such an awesome nature event. I spent 3 months on the Eastern Shore of Virginia surveying the Monarch migration in 2005, my best find was only 1500 in a roost. I tagged 550 that summer, none were recovered... I did get some pretty good photos, one day I'll add them to my blog.

  8. Randy, that's sounds like a great experience! 1500 butterflies in one roost sounds impressive to me. I hope you do add the photos to your blog, I would like to see them.
