The capsules varied in size from 1/2" in diameter & 2" in diameter. The larvae were about 1" long, light green in color, with 2 black longitudinal marks down the back. The dark eyes were very prominent. The larvae were able to move about within the capsule.
When the adults were seen swimming,
it was noticed that they use the tail almost exclusively — the hind limbs are held back beside the tail, and forward movement is caused by lateral undulations of the tail.
