How to Attract Giant Silk Moths
Giant Silk Moths have become my absolute favorite things to raise. Why? The caterpillar phase is lengthy and their growth is phenomenal. They are voracious eaters. A healthy caterpillar is firm, has a tremendous grip and its substantial size makes it easy to observe and appreciate.
Moth Night Life
The adults are present in decent numbers, but we never see them since moths fly at night. It is a marvel that something so beautiful, so close by, goes unseen.
Since the life of a Giant Silk Moth occurs mostly in high treetops, my method for obtaining and raising them is different than for butterflies. It is unlikely you will net a moth unless you set up a night vapor light and white screen – a very viable option, but not practical for my home.
Start with Cocoons
I personally started my stock with cocoons I ordered from a reputable Silk Moth farmer online. USDA guidelines are such that although you can purchase from out of state and raise four species in Illinois (Luna, Cecropia, Polyphemus and Promethea) you can never let out of state Moths fly free. They cannot be released, and must live out the remainder of their life in captivity. I purchased the cocoons, and when I had a female moth eclose, I allowed her to mate with a wild, local male moth. The eggs she laid, became caterpillars which I hand raised. This second generation, who had local parentage could be released. That is how I developed my initial stock.
If you live in Illinois and would like to raise Giant Silk Moths, please contact me for eggs, caterpillars or cocoons. If you live outside of Illinois and would like to try this, let me know and I will share my colleague’s contact information with you.
