Yellow Swallowtail butterfly. - a photo on Flickriver

            The eggs are deep green, shiny and spherical. They are laid singly, on the undersides of leaves. The caterpillars emerge about four days later. Young caterpillars resemble bird droppings, and as they molt they eventually turn bright green, with a pair of large yellow eyespots with black and blue pupils. They can feed on the leaves of a variety of trees, and the predominant foodplant varies across their range; trees commonly used include cottonwood, willow, quaking aspen and many others. The caterpillars molt 5 times, eventually reaching a length of up to 5 cm before pupating. In summer, the butterfly can emerge as little as 15 days after the caterpillar pupated, but when the caterpillar pupates in the fall, the butterfly will not emerge until the spring. The chrysalis is green in summer and dark brown in winter, and looks like a piece of wood.  Yellow Swallowtail butterfly. (Papilio rutulus). From my garden.
