Hi Daniel,
I was just about to give up and let you know I couldn’t find a single Monarch Chrysalis when I spied one! Wasn’t even looking for it this time. So, there were 16 total caterpillars of varying ages. There are five left now, one larger and four of medium size. The very first hatched the day before Thanksgiving. The large caterpillars have been disappearing into the Cigar Plant bushes one at a time over the past week. Hope your holidays were great and I’ll be keeping an eye on this gem now that I’ve found it!

Monarch Chrysalis

Happy New Year Anna,
Thanks for sending us this photo of a beautiful Monarch Chrysalis.  We hope the other mature Monarch Caterpillars wandered away from their food plants to metamorphose in a different location and you have just not been fortunate enough to spot them.

Daniel,
Happy New Year to you and yours!  Thanks for the kudos on the photo.  I’m beside myself, which, according to certain members of my family, is a dangerous thing!  I have no idea why this fourth generation of caterpillars took so long to pupate.  I’ve read that the butterflies from this generation live 6-8 months so they can make the journey southward, but nothing on the caterpillars themselves.  Can you shed any light on this?

Hi Anna,
Cool weather slows down the metabolism and consequently the growth rate.  We suspect that might be the cause of the extended period of time in the larval state.

Hi Daniel,
Thanks very much.  I suspected the same.
