You know you are bored when you count your feeder insects!
My Indian Sticks are doing well, and I picked up some info on feeding Indian Sticks that may be helpful.
When you get blackberry cuttings, cut off the new lighter green growth and throw it away, supply the darker leaves. The new growth has a different chemical makeup which is not beneficial to sticks.
Also, you can use oak leaves as well during the spring and fall. I also raise ET, the stick that looks like a scorpion, also known as Australian Sticks, and oak leaves are supposed to make stronger egg casings for them as well. I don't feed the ET's off, they are quite prickly, but they are great for kids to handle as they don't kick as a defense or spray as some of the sticks do.
