Wooden Growth Charts


     The newly hatched butterfly clings to its chrysalis for 30 minutes to an hour, during which time the fluids in its swollen abdomen are pumped into the wings.  The wings straighten and grow to their full size as they fill, and the abdomen shrinks to its familiar long, thin shape. During the life of the butterfly, this fluid is circulated between wings and abdomen; it functions as a blood supply. 

     Once the butterfly has achieved full size, and its wings are stiff and dry, it will usually move from its perch on the fragments of its chrysalis to the branch or other surface to which the chrysalis is attached.
