If you want to gently remove them , taking care not to pinch or crush the pupa inside , you can keep them in a terrarium or large pickle jar with some nice sticks to climb up on , in the garage or other unheated but sheltered place , and have a good chance to see them emerge . If they are alive and inhabited , they should be somewhat heavy , have no holes in the cocoon where a moth or parasitic wasp could have emerged , and occasionally wiggle around inside making dryleafs noises . <| sep |> I ' m thirTEEN that means TEENager you friggin DOLT !

My father employes circa 5000 people in rural Georgia . Without my father ' s entrepreneurial abilities and capitalism , those people would be out of a job . Furthermore , under Obama . do you know what many rich families did ? We invested our money in foreign countries . In the end you have two options , give us tax breaks and allow our businesses to foster , which allows the common people to prosper too . Raise taxes and regulations and watch us go overseas with jobs and money .
