Figure 28. Sequential frames (1-25, 25 fps video) showing each position of the opisthosoma during the close fan dance of a male Maratus aquilus in front of a female, viewed from the rear. Each arrow indicates movement of the opisthosoma relative to the preceding frame. 3-13, 20-25, Low amplitude movement of the partly elevated fan near the center position with flaps retracted. 15-18, Two wave cycles to the right with the right flap extended.

Figure 8 in Courtship display of the peacock spider Maratus aquilus (Araneae: Salticidae: Euophryini)
Figure 8. Selected frames (1-25, 25 fps video) showing an elevated fan wave display by a male Maratus aquilus. With legs III extended in an upright position, the flaps of the fan were displayed alternately on either side in a manner similar to that seen in the close fan dance (~3.5 lateral wave cycles/s). The female, facing the male, is visible as a blurred figure in the foreground (lower right) of each frame. Here as in subsequent figures movement of the fan or legs relative to the preceding frame is identified by an arrow. 4-11, (1.20-2.16s), 4 wave cycles to the left over ~1s. 13-24, (2.68-4.56s) 6 wave cycles to the right over ~2s.
Figure 25 in Courtship display of the peacock spider Maratus aquilus (Araneae: Salticidae: Euophryini)
Figure 25 (continued from previous page, continued on next page). Selected sequential frames (1-80, 25 fps video) showing the close fan dance of a male Maratus aquilus from the perspective of a closely attending female (blurred image in foreground). 25-37, 6 wave cycles to the left.
Figure 7 in Courtship display of the peacock spider Maratus aquilus (Araneae: Salticidae: Euophryini)

Figure 20 in Courtship display of the peacock spider Maratus aquilus (Araneae: Salticidae: Euophryini)
Figure 20. Sequential photographs (1-4) showing a female Maratus aquilus turning from side to side to follow the close fan dance of a male. As with other members of the vespa group, legs IV are extended far to the rear during this display, allowing for movement of the fan toward each side of the elevated legs III.
Figure 25 in Courtship display of the peacock spider Maratus aquilus (Araneae: Salticidae: Euophryini)
Figure 25 (continued on next page). Selected sequential frames (1-80, 25 fps video) showing the close fan dance of a male Maratus aquilus from the perspective of a closely attending female (blurred image in foreground). Arrows indicate movement of the fan relative to its position in the preceding frame. The partly elevated fan was first waved for 2-7 cycles (3-4 represents one wave cycle) to one side, then centered, then waved for 2-7 cycles to the other side. The duration of each of these cycles averaged 0.193s. Most of the time (14.32s of 19.72s or 72%) the fan was moved up and down and from side to side through a low amplitude at the center, displaying the iridescent posterodorsal fan ornament through the window between legs III. 3-6, 2 wave cycles to the left. 10-22, 6 wave cycles to the right.
Figure 6 in Courtship display of the peacock spider Maratus aquilus (Araneae: Salticidae: Euophryini)
Figure 6. Unilateral (1) and bilateral (2-5) semaphore displays by male Maratus aquilus. Note variation in extension of flaps and elevation of the fan during bilateral display.
Figure 2. Nine different living adult male Maratus aquilus. 2 in Courtship display of the peacock spider Maratus aquilus (Araneae: Salticidae: Euophryini)
Figure 2. Nine different living adult male Maratus aquilus. 2, The posterior part of the fan can be elevated when the fan is partly elevated as shown here. This makes the iridescent green posterodorsal ornament of the fan (Figure 3:11) visible from the front.
Figure 1 in Courtship display of the peacock spider Maratus aquilus (Araneae: Salticidae: Euophryini)
Figure 1. Known distribution for peacock spiders of the Maratus vespa group in Western Australia. At present each species appears to have a limited, parapatric distribution with respect to other members of the group. Future studies should reveal additional vespa group species in this coastal region, spanning little more than 200 km. Background courtesy USGS/Landsat.
Figure 3 in Courtship display of the peacock spider Maratus aquilus (Araneae: Salticidae: Euophryini)
Figure 3. Detailed views of the fan of living adult male Maratus aquilus. 1-3, 5, Elevated fan with flaps extended during display. The iridescent green colour of the posterodorsal ornament of the fan is scarcely visible in this orthogonal view. 4, 6-9, In this perspective the folded fan resembles the head of an eagle (aquilus). 10, Lateral view of opisthosoma showing folded fan of a mating male. 11, View of the iridescent green ornament (inset at upper left) through legs III as seen by a female attending to the close fan dance of a male. With the posterior fan only partly elevated, the fan presents at an angle that appears to increase the intensity of light reflected from this ornament. To the rear, or just above the iridescent green scales of this ornament, lies a small patch of brighter, light blue iridescent scales. In this position the fan is also waved and moved up and down through a low amplitude. 12-14, Ventral views showing flexible articulation of the pedicel and the opisthosoma.

Figure 23. Photographs showing the close fan dance of a male Maratus aquilus in front of a female. 1-3, Lateral views of this display. Note the elevation of the posterodorsal fan ornament when the partly elevated fan is held at the center position (1, 3). 4-10, Sequential rear views of this display showing alternating extension of the lateral flap on either side.
Figure 15 in Courtship display of the peacock spider Maratus aquilus (Araneae: Salticidae: Euophryini)
Figure 15. Consecutive frames (25 fps video) showing movement of the fan and extended legs III during the active fan dance of a male Maratus aquilus. 2, 16, Each large arrow identifies a step to the spider's right side as the lead leg III was raised to a near-vertical position.
Figure 27 in Courtship display of the peacock spider Maratus aquilus (Araneae: Salticidae: Euophryini)
Figure 27. Sequential frames (1-15, 25 fps video) showing alignment of the midline of the turning female (white lines) attending to the close fan dance of a male Maratus aquilus. Frames are from an ~80s display sequence that included ~13 center-to-right-to-center-to-left-to-center cycles (~6.2s/cycle). Most of the time the fan was displayed in a center position (1, 3, 5) and moved up and down or sideways through a small amplitude.
Figure 19 in Courtship display of the peacock spider Maratus aquilus (Araneae: Salticidae: Euophryini)
Figure 19. Photographs depicting typical positions associated with the active fan dance of a male Maratus aquilus. 1- 3, Lateral rotation of the fan during an active fan dance can resemble its movement during the close fan dance, but legs III are not drawn together to a central position. 4-6, 8-9, 10-13, Each of these sequences shows movement of the male toward a female (blurred image in foreground).
Figure 14 in Courtship display of the peacock spider Maratus aquilus (Araneae: Salticidae: Euophryini)
Figure 14 (continued on next page). Selected sequential frames (25 fps video) showing continuous movement of the fan and extended legs III during the active fan dance of a male Maratus aquilus. The female (blurred image at lower left) was directly in front of this male. 7, 20, Each larger arrow identifies a step to the spider's left side.
Figure 26 in Courtship display of the peacock spider Maratus aquilus (Araneae: Salticidae: Euophryini)
Figure 26. Sequential frames (1-15, 25 fps video) showing each step of the close fan dance of a male Maratus aquilus from the perspective of an attending female (blurred image at lower right). 5-12, 4 wave cycles to the left.
Figure 13 in Courtship display of the peacock spider Maratus aquilus (Araneae: Salticidae: Euophryini)
Figure 13. Consecutive frames (25 fps video) showing continuous movement of the fan and extended legs III during the active fan dance of a male Maratus aquilus. The female (blurred image at lower right) was in front of, but not facing, this male. 1-4, Fan lowered as legs III moved to a vertical orientation over 0.12s. 4-20, Slow lowering of legs III as fan was waved over the next 0.64s (fan rotated at a rate of ~3 left-right cycles/s). Note the position of the pedipalps in front of the chelicerae.
