This is a homemade $2.00 butterfly cage made from wedding veil mesh material from Joan Ann Fabrics waiting for the butterflies to hatch. Purchased 3 feet and 4 inches of material and made cardboard disks from a grocery store cardboard to 1 foot in diameter. The length of the material stapled around the disk was calculated from the circumference of a circle or πd or 3.14 X 1 which is equal to 3.14 feet or 3 feet 4 inches. The fabric was stapled around the disks and rubber banded at the top and bottom. String and tape were used to hang the cage at observation level. The DIY cage compared to $8 commercial cage. This DIY could significantly lower the cost of the project for student.
