Assignments Pictures Of Butterflies

Monarch butterflies are known for the incredible mass migration that brings millions of them to California and Mexico each winter.

North American monarchs are the only butterflies that make such a massive journey—up to 3,000 miles. The insects must begin this journey each fall ahead of cold weather, which will kill them if they tarry too long.

Monarch butterflies begin life as eggs and hatch as larvae that eat their eggshells and, subsequently, the milkweed plants on which they were placed. (Monarchs are dependent on milkweed plants, which larvae eat nearly exclusively.)

Fattening larvae become juicy, colorful caterpillars, then create a hard protective case around themselves as they enter the pupa stage. They emerge as beautifully colored, black-orange-and-white adults. The colorful pattern makes monarchs easy to identify—and that's the idea. The distinctive pattern warns predators that the insects are foul tasting and poisonous.

Butterflies that emerge from chrysalides (pupa state) in late summer and early fall are different from those that do so during the longer days and warmer weather of summer. The monarchs that emerge later are born to fly, and know because of the changing weather that they must prepare for their lengthy journey.

Only monarchs born in late summer or early fall make the migration, and they make only one round trip. By the time next year's winter migration begins, several summer generations will have lived and died and it will be last year's migrators' great grandchildren that make the trip. Yet somehow these new generations know the way, and follow the same routes their ancestors took—sometimes even returning to the same tree.

Many scientists are concerned about the eastern population of monarchs, which summer east of the Rocky Mountains. This group is occurring in ever smaller numbers, and its survival may be threatened by a series of natural disasters in the Mexican wintering grounds, as well as by reduced acreage of milkweed plants in their summer home.

Spring has sprung in the northern part of the world and the creep crawly things are out and about. But they aren’t all bad or ugly. Many of the world’s smallest creatures are quite attractive – beautiful even.

So here is how some photographers chose to capture them in butterflies and bugs:
