Abstract
This protocol describes a simple locomotor assay in Drosophila melanogaster. In brief, the locomotor of each single fly in the culture dish is recorded by a web camera. The moving time, walking length, speed and the locomotor trails of the single fly could be quantitatively analyzed.

Background
This protocol was implemented in the previously published study (Liu et al., 2016). In that study, this assay was combined with the optogenetic system by simply providing the proper excitation light.
