There is so much attention these days on creating pollinator gardens and wildflower meadows, but too many times these articles and posts fail to grasp the most important part - that butterflies do not need nectar sources nearly as much as they need a host plant to raise their young. When your total lifespan is likely to be less than a week as an adult, it is absolutely critical that you don't waste time producing the next generation.   Butterflies are especially adept at finding their host plants. It is an evolutionary necessity.  Plants emit volatile organic compounds (VOC's) into the air and adult female butterflies are drawn by these chemicals to locate their suitable larval host plants. They don't do this to find nectar as it ...
