After wasps murdered the Black Swallowtial caterpillars that were munching on dill plants in our garden, it was time to take action to rescue the Monarch caterpillars that were dining on our milkweed plants. These caterpillars should be well along in their development as we still have very small caterpillars (the diameter of hair) on the milkweed plants in the garden. Updates will be added as the caterpillars progress, hopefully, into butterflyhood.
Two days after the above pictures were taken, the two caterpillars attached themselves to the screen that covered their enclosure and hung in a "J" shape. Over a period of a few hours they transformed into the pupa stage (chrysalis).
