Swallowtail Butterfly Caterpillar Spins Silk Suspension Loop V22343

- This documentary compilation shows a Western Black Swallowtail (Papilio polyxenes coloro) butterfly caterpillar "strapping" itself in with its own silk for the pupation process, where it sheds its final skin and becomes a pupa or "chrysalis".
Unlike its eastern counterpart, the chrysalis phase of this deep-desert dwelling butterfly's life cycle can include a hibernation period (known as "diapause") which can last 7 years or more in drought conditions, so selecting a proper site is critical for survival.
The caterpillar can wander for several days searching for a suitable location which is shielded from predators, high winds, feezing winter cold, and daytime summer temperatures which can exceed 140 °F at ground level. In most cases, this species selects a rock crack or other crevice between or under large boulders to protect itself from the extreme conditions.
Next, the caterpillar must attach itself to the selected location, which can be a vertical surface or even upside-down under a rock. It begins by spinning a silken pad on the chosen surface with a small silk mound or "button" at the tail-end of the pad to which it will anchor its tail. This part of the process is already completed when filming was started for this series. Then, as shown in these scenes, it spins a silken loop around its midsection to secure the upper part of its body. The loop is attached to the surface on both sides of the caterpillar's body. It works back and forth from one side to the other, each time adding another strand to the loop which becomes noticeably thicker as 15-20 or more strands are added. The finished loop is quite thick and some of the individual strands can be seen. When finished spinning the loop, the caterpillar ducks its head under and into the loop, then works it down to the proper location on its body where it becomes captured in the folds of its skin. A couple of days later, pupation occurs as the caterpillar sheds its final skin to begin the chrysalis phase of its life cycle.
These scenes were filmed in high resolution 4K/UHD macro with a Sony FS700RH and Convergent Design Odyssey 7Q+ digital recorder. The camera angle was changed a number of times during the process to show the caterpillar's efforts in as much detail as possible.

What's that surface? Skin?
It's actually thin cardboard - the inside of a paper towel tube. The extreme magnification shows all the detail in the paper so it may look a bit different than one might expect. More detail: These caterpillars prefer a dark, secluded place to go through metamorphosis, so in the lab/studio I place them inside these paper tubes and cover the top (with more cardboard) to make it dark inside. The caterpillar wanders around a bit (as they're programmed to do) but settles down quickly since the location is pretty much what it wants. Once it has selected a spot inside the tube and makes its silk pad, I can cut the cardboard tube apart and mount the piece with the caterpillar on it in front of the camera for filming the rest of the process. Thanks for checking it out! =)
