Consider a butterfly hibernation box in your backyard. A butterfly hibernation box is a tall, slender wood box with vertical slots on the front to allow butterflies access inside. This will provide a roosting shelter for adult butterflies or a winter home for butterflies that overwinter in the area. Your butterfly hibernation box should be placed low to the ground and close to your designated butterfly plants. Add a few vertical strips of bark or twigs to your box to give adult butterflies something to cling to inside your box.
Hilltops are the butterfly equivalent of singles bars.
Male butterflies will patrol hilltops looking for females. Place your large or decorative rocks in sunny areas. Butterflies are cold blooded and like to warm themselves in the sun. And lastly, try to suspend your use of chemicals in your butterfly garden. Many commercial insecticides are lethal to butterflies and caterpillars, not to mention the damage they cause to our environment.
