For Father’s Day 2021 I received cages for raising Monarch butterflies. A large zippered door is a great feature, one side of the cage drops away for easier access and photography. Here are some photographs of the developing chrysalis and emergence.
In the first step of chrysalis development, the caterpillar climbs to a chosen location and weaves a silk pad from the abdomen. We are looking down on the caterpillar through the top of the woven material that forms our cage. The silk pad is a small white dot to the right.
Click photograph for a larger view and use Ctrl-+ (press down Ctrl, hold, then click plus sign repeatedly) to zoom in closer.
After the silk attachment pad is complete, the caterpillar releases itself to hang in a shape of the letter “J.”
The caterpillar sheds the outer skin as the chrysalis forms around it.
Just prior to emergence the chrysalis turns from opaque green to translucent Iappears dark). Here the wing pattern and body markings (white dots) are visible.
I used a Manfrotto tripod, the Canon EOS 5D Mark IV dslr (high resolution video capability) and Canon’s EF 100mm f/2.8 USB macro lens for the following up close coverage of a Monarch emerging followed by wing expansion.
