..., allowing subsequent 3D reconstruction of the hoverfly and bead position as a function of time. We show that male E. tenax hoverflies are unlikely to use strict heuristic rules based on angular size or speed to determine when to start pursuit, at least in our indoor setting. We found that hoverflies pursued...

...; however, the vertices on the interior portion of the wings were aligned to the marker points in the images in the same fashion and the same parametric surface interpolates between them, so this metric is a good indicator of the overall accuracy of the 3D reconstruction method. Fig. 4 shows an example...
