Metamorphosis in Action
Rob noticed this caterpillar beginning to form a chrysalis on a shepherd’s crook in the garden. We had seen a large 5th instar crawling around yesterday, a few feet from the milkweed plant. It must have assumed the J position overnight. The wiggling is for real – not the wind!
I was curious as to why we’ve only seen two chrysalides after seeing 12-15 caterpillars over the past few weeks. Apparently, the caterpillars and eggs have quite a few spider and ant predators. Due to predation and other environmental factors, only a small number (5-60%) make it through to adulthood. Also, several insects, e.g., large milkweed bugs and tussock moth caterpillars, compete with Monarchs and eat the leaves and flowers.
More soon!
