Life Cycle
There usually are two to three broods in a year, but in northern areas, the species may be univoltine. In some places such as the UK, some will pupate and emerge in the same year and others will overwinter as pupae before emerging the following year, a situation known as being partially bivoltine.
The caterpillar spends the first part of its life with the appearance of a bird dropping, an effective defense against predators. As the caterpillar grows larger, it becomes green with black and orange markings. It has a defense against predators in the form of an osmeterium, which consists of retractable, fleshy projections behind its head that can release a foul smell if disturbed, which deters insects, but not birds.

Famous quotes containing the words life and/or cycle:
“Why should not our whole life and its scenery be actually thus fair and distinct? All our lives want a suitable background. They should at least, like the life of the anchorite, be as impressive to behold as objects in a desert, a broken shaft or crumbling mound against a limitless horizon.”
—Henry David Thoreau (1817–1862)
“The lifelong process of caregiving, is the ultimate link between caregivers of all ages. You and I are not just in a phase we will outgrow. This is life—birth, death, and everything in between.... The care continuum is the cycle of life turning full circle in each of our lives. And what we learn when we spoon-feed our babies will echo in our ears as we feed our parents. The point is not to be done. The point is to be ready to do again.”
—Paula C. Lowe (20th century)
