- Abstract
The dispersal behavior of the larvae of a leaf beetle, Galerucella nipponensis, was investigated to analyze the dynamic interaction between the leaf beetle and its aquatic host plant, Trapa japonica. The hatchlings dispersed from the hatched leaf to other leaves in a rosette within 12 h. Some larvae even dispersed on the water surface. As a result, the hatchlings distributed uniformly within the rosette. This larval dispersal appeared to be adaptive behavior responding to a rapid turnover of T. japonica leaves. The female adults preferred young or middle-aged leaves to old leaves as oviposition sites.
