My friend Lauren, who raises Monarchs, and who also creates beautiful and highly productive butterfly and songbird habitat gardens, shared this very cool photo of empty Monarch chrysalides. Thank you Lauren!
When a Monarch caterpillar is preparing to pupate, it first spins a silky mat from its spinneret. The silk is much like the texture of spider’s silk and extends over an area several inches in diameter. You can see in the diagram below where the spinneret is located.
