Figure 31. Consecutive video frames (1-10, 25fps, exposure/frame 20msec) showing one cycle of up and down movement (~2.5Hz flicker) of the pedipalps of a male Maratus sceletus. Pedipalp movement relative to the preceding frame is indicated with arrows. Movement of the pedipalps is generally synchronous and bilaterally symmetric. They are often raised in more than one step (in this example in two steps shown in frames 2-3 and 6), then rapidly lowered (frame 9). This display may occur in the absence of a female, as shown here, or as a component of the fan dance. As in other salticids, this frequent flicker appears to advertise the presence of the male even when he is stationary.
