This little butterfly is fast, easy and very interesting to raise. At the time of the year when you see this butterfly, go check the stinging nettles and look for a silk net at the top of a plant. The silk netting the caterpillars have made to protect themselves from predators or parasites will be full of larvae.

Take a box, slide it ever so gently under the plant because the caterpillars will let themselves fall to the ground if disturbed, then cut the top of the plant so it falls into the box with the larvae.

Separate the caterpillars twenty per rearing cage and feed them stinging nettles branches stuck in little water viles like they use at the florist. Clean and feed every day. In no time they will turn into pupae and a week later you will have many butterflies.
