The Painted Lady Butterfly eggs arrived from Carolina Biologicals in a small centrifuge tube. I ordered 30 of them but later found out there was about 60 in the tube. The color of the eggs appear to be aqua blue. I found them smaller that I expected them to be, and wondered how they got them off of the growth media so neatly. It seems that they would be hard to find on a host plant, and it would take a magnifying lens to see them. However, the distinctive color of the eggs should make them easy to recognize now that we know what they look like. It would be interesting to learn how the laboratories grow these eggs.
