摘要
A diurnal vertical migration of larvae of C. punctipennis (Say) was observed in shallow temporary woodland pools in east Texas [USA]. In the laboratory, in 153 cm tall columns, the larvae underwent a much greater migration than possible in the shallow pools. The migratory behavior and transparent body of Chaoborus larvae may have originally evolved in such shallow water habitats. These traits enabled Chaoborus to successfully invade the different adaptive zone of predation in the plankton of deep lakes.
