Abstract: The behavior of creature of nature is complicated and random, especially bee, a kind of colonial creature. However, the complicated structure of bee colony is generated by the interaction of single behavior of bee. By the research of the artificial life theory and some outstanding feature, the graphic VB program simulates the behavior of bee's collecting pollen. The program only simulates the behavior of individual bee's collecting pollen, but achieves the integral behavior of bee colony. Our research shows the important feature-Emergence-of the artificial life, that is, emergence.
