These butterflies are a marvel. Amazingly, they are migratory! They overwinter in Mexico and southern California, and in February start to migrate north. They breed and lay eggs in the southern USA. The progeny from those individuals fly farther north and the process is repeated , with monarchs coming as far north as southern Canada. In August, they turn around and head south. The generation that overwinters lives up to seven months, while the others live only 2-3 months. This is explained much more clearly in Wikipedia at this site. Please click on the images to see the details.

|Aesclepias spp., especially this A. tuberosa, have toxins that the Monarchs accumulate in their tissues.|
|Most butterfly predators are sensitive to the toxins and have learned to avoid these brightly colored butterflies and their equally brightly colored caterpillars.|
|With a close up look here you can see stripes and even the hint of a caterpillar face at the tip of the egg.|

We specifically planted the butterfly weed to support these butterflies. It has been such a great pleasure to see and photograph the monarchs at the northern extent of their range. Butterfly weed has been included in many wildflower projects in these parts of the US, so on this end of the migration, things are pretty good. Unfortunately, on the southern end where they overwinter, deforestation is putting monarch butterflies at risk. It thrills my soul each year to see the monarchs arrive and further the species for at least another year; and this year has been a banner year indeed.
Beautiful images of a beautiful butterfly.ReplyDelete
They really are a stunning butterfly Wilma.ReplyDelete
Excellent captures of them.
I hope they continue to thrive, despite the wrecking of their wintering grounds.
Beautiful images very sharp and fantastic detail.ReplyDelete
A lovely series of a beautiful butterfly Wilma. I have seen them several times on nature TV programs but it must be much better to see them for real.ReplyDelete
Wow what a wonderful beast this butterfly.. Wow you got a very beautiful set of pictures of a wonderful butterfly... Well done Wilma!ReplyDelete
Dean - thanks, glad you like them.ReplyDelete
Keith - thanks. They overwinter at specific sites in Mexico where thousands of them cluster together on trees for warmth. They are very susceptible to logging and development.
Anthony - they are often very cooperative and let you get quite close for photography, and of course the caterpillars are easy to keep up with. ;-)
John - The colors are so rich that TV and photos don't do them justice. thanks for visiting and commenting.
Chris - Thank you for your kind comments. They are beauties, aren't they?
