This answers my main and 1 of my sub questions! Jun 28, We hope you'll visit again soon! Noel Jun 25, OK one day I noticed a caterpillar on one of my tall plants in my backyard. I noticed each day that it was climbing a little higher and higher until it finally turned upside down and formed a cocoon.
But this cocoon wasn't like any I'd ever seen pictures of and I thought that something must have gone wrong and it died. But I was wrong because about a week later it opened up and four more very small caterpillars that looked identical to the first one were all of sudden hanging out on the stems nearby!
And now two of those have made cocoons that look just like the first one and a third is in the process of getting ready to go into its own cocoon as Well! I've looked everywhere on the Internet to find something about this. But everything I read tells me that after the cocoon comes the butterfly!. But that's not what is happening here and I can't find any info on this anywhere!. My friends and I are starting to think I've found an alien bug! Can you explain to me that this is possible and it's not a new species or something?

The caterpillar period lasts about two weeks, and the rest of the lifespan of the insect once in imago stage is only about two to six weeks in the first three generations in any given summer. The fourth generation will migrate south and live for six to eight months.
Many moths also have a pupa stage in which the insect will enclose itself in a cocoon. The luna moth, for instance, has a pupal duration almost identical to that of the monarch butterfly. That is, he will remain in his cocoon for about two weeks before emerging in imago stage. The gypsy moth, a severe agricultural pest, will only sometimes spin a cocoon. When he does, it is generally flimsy, only enough to hold together the leaf on which it rests.
Their pupation lasts 14 to 17 days. This duration is common to most moths, and is often only extended in unfavorable circumstances. One of the most economically significant insects is the silkworm. This worm will eventually become a moth, after he has proceeded through his metamorphosis.
