Found my first male IO Moth had eclosed today after the 3rd female eclosed yesterday. The male seems a bit smaller than the females...
Little beats some of our moths for beauty when freshly eclosed.
Most of the Giant Saturniids are sexually dimorphic. Not just coloration, but male to female size.
Nature is frugal.
The female ecloses with the eggs formed and ready for fertilization. She needs the extra size to be able to carry fat and the eggs. The fat gets her thru the week to ten days while a mate finds her and she can lay her eggs. These moths have no mouths as adults, no eating.The male finds her, most times, before she flys, by following a phenomenon trail up to a mile long.
Two ways to get her to mate are:
1). Tie a piece of thread around the wings next to the body. Form a loop, not too tight, but too small for wings to slip thru.
Tie her out in an open area and a male may find her and mate.
Or, a tricky way.
2) There are four hard claspers just inside the anal opening of the male. Spread these with tweezers and place the end of the females abdomen between them. The male may clasp it and mate.
Reguardless of method, after she is mated put here in a paper lunch bag and fold it closed. Put it in a dark place. Check a few times a day for eggs. Wait till she dies before giving up, as it may take a week.
If you get eggs, snip them AND A PIECE OF BAG free and put it on fresh food plant and watch them hatch and grow.
I have raised many of the showy moths and butterflies from around Maryland.
Luna moths are the easiest, have three generations (in captivity), and if you have seen one, imagine 50 or more let off at once. I did this for the neighborhood kids once. After that, it was done for the neighborhood. This was before releasing butterflies at weddings became popular.
I hope I am forgiven for being long winded. There is even more to be explained, but this is enough to start a hobby that will never cease to provide you with entertainment and photo opps.
Start with Monarchs. They need help, and food plants are everywhere.
Enjoy.
