Insect Lore is the Original Butterflies-By-Mail Company. We have been delivering the Magic of Metamorphosis to families and classrooms for almost 50 years! We take great pride in the quality of our educational products and the reliability of our Live Insect Kits. However, nature can be unpredictable and the hatch rate is not always 100%. That's why we guarantee 3 out of 5 caterpillars will develop into adult butterflies, and 5 out of 10-13 ladybug larvae will develop into adult ladybugs.
