CERCOPIA MOTHS
    

  Our cecropia cocoons were purchased  from  William Oehlke.  He has a  great website, Giant Silkmoths of Prince Edward Island, Canada, http://www3.islandtelecom.com/~oehlkew/izsaturn.htm .  It is a fantastic resource of information about the giant silkmoths.
  Mrs Gray brought in the cocoons to school on April 12. She placed them  in a modified net laundry basket. Mrs. Gray had removed the side with a pocket and sewed tulle in its place.  She had closed the open end with a piece cut from the pocket side.  She had sewed part of the piece onto the opening and used velcro to close the rest of the opening. This allows us to safely open and close our cage.   
cocoons
Cecropia caterpillars create a double walled cocoon.   This means that it first spins and outer shell and then spins an inner portion of the cocoon.

Our first cecropia has emerged.  It is a huge male. Do you see his big feather-like antennae? He is so beautiful and soft looking.

The Cecropia Moth
Cecropia silkmoth (Hyalophora cecropia) or Robin Moth
Cecropia's range is the eastern half of the US. From mid-Texas to Florida to Maine to Minnesota. Cecropia moths are our largest lepidoptera with wingspans of of 4 5/16” - 6" or more.
Depending on the size of the moth, female Cecropia moths lay approximately 250 - 350 eggs. Cecropia eggs are generally laid out in short rows, often in rows of four. The eggs hatch in about 14-20 days.

The caterpillars eat box elder , sugar maple , cherry, plum , apple,  alder, birch, dogwood , willow, lilac, elm, glossy buckthorn, oval-leafed privet, black walnut. When Cecropia caterpillars first hatch they are black. Once they shed to 2nd instar they turn orange. Then in 3rd instar, the larva are either orange with red tuberacles, or green with red tuberacles.

In the 4th and 5th instar they are green with yellow, red, and blue tuberacles. Young caterpillars feed in groups on leaves and  older caterpillars tend to eat alone.

    Cecropia caterpillars usually attach their cocoons along a twig of a plant they're feeding on. Cecropias have only 1 brood a year.The moths usually emerge from their cocoons  in the late morning. It’s unusual to see one hatch out after 2 pm.

The body of the adult  is red with a white collar and white bands on the abdomen. The wings are dark brown. The forewings are red at the base. Crescent spots and the area by the body are red on all wings.  The males are easily identified by their wide, feathery antennae. The female has a heavier body and has thinner antennae. They will almost always mate the first night.
