Two years ago I had been given this set once and found it so beautiful that I have once again ordered me this year. The requirement of the crawler with the voucher went smoothly and the caterpillars delivery came as desired. All five caterpillars were doing well and then grew daily zusehens ... and now after a week are already two chrysalis, the other three will be probably a chrysalis in a few hours ... I could watch the caterpillars for hours and my kids are fascinated by it and run continuously to the cup so. Morning when everyone chrysalis, I will put them into the butterfly garden and then wait again and watch ... and hope that hatch from all beautiful, healthy butterflies. :)
