Termites may be found in decaying logs and stumps in wooded areas. When it gets too dry they burrow down in the soil looking for moisture. They can also be ordered from Carolina Biological. Termites may last a few weeks if they have wood and are kept moist. I had couple of generations and was able to keep them going the whole year with very low maintenance.
Some butterflies taste with their feet.
When a butterfly lands on a flower, the petals, which are faintly sweet, are sensed by the taste mechanism on the feet. The reaction causes the long tubular mouthpart to uncoil and probe down into the nectar. There are ticks that may live one to three years without feeding but when they find a host, they become filled with blood in a few days. There are over a million species of insects. There are over 90,000 species of insects in North America.
