Unlike your museum, it will require daily care. Your insects will have a much better chance of survival if their new habitats are prepared several days in advance. Place 2 inches of potting soil in several small aquariums or plastic containers. Seed heavily with rye grass, water well, and place in a sunny window. Within a few days you can put crickets and small grasshoppers in your pastures.
Crickets also like small bits of paper, egg cartons or pieces of cloth to chew on.
Always keep a second pasture growing so that as food becomes scarce you can transfer your insects immediately. While your pastures are growing, prepare a number of various sized live cages for your insect pets. One of the easiest and most utilitarian cages I have found was designed by Jim Kerrigan, a Scottsdale Portal Leader. Cut the bottoms from two gallon bleach bottles, about 2 inches from the base. Poke a small hole in the center of each.
