Actually, you don't really have to hunt for them at all. There are some shrubs outside of our building that seem to be a perfect habitat for ladybugs. Armed with a 100mm macro lens, tripod and a collapsible reflector, I tried to get a few photos of the ladies. They don't move around a whole lot, so they are fairly easy to photograph. I had one shot set up perfectly, but just as I was pressing the shutter, it flew away. The result was a cool photo showing a ladybug like I have never seen before. It's amazing how those tiny wings fold up so precisely under that fragile little shell.
