I don’t know much about Australian jumpers but to my untrained eyes it looks like Maratus mungaich, which live in Western Australia.

Hi yes, I have messaged you privately with some details.

More than just a pretty butt and flamboyant display.

Full info of Maratus https://animaldiversity.org/accounts/Maratus/#communication

Technical - mating display. Neurostimulation from the central nervous system that simultaneously triggers muscular contractions in the anterior region of the cephalothorax adjacent to the third pair of legs. These contractions in turn stimulate multiple physiological functions:
1. Hydraulic pressure which causes the third pair of legs to assume the hyperextension position.
2. Causes the adjacent abdominal muscles to contract extending the opisthosomal flaps.
3. Causes the the third and fourth pair of legs to vibrate sending vibrations both through the air and the surface the animal is on. A mating call so to speak.
4. Releases pheromones to aid in attracting females.

What is especially interesting is these four functions which ordinarily originate in unrelated locations of the brain operate in concert to produce this mating display. The first three are neuromuscular but the pheromone release involves the normally unrelated endocrine system. Along the lines of patting your head while rubbing your stomach while standing on one foot wiggling your toes. Possibly the endocrine system triggers the other physiological responses.

As a bonus, the eyes of Maratus are dialed in to the UV spectrum which the iridescent opisthosomal flaps reflect. Eyesight capability most commonly found in birds. Thus these mating displays are only effective during daylight hours when there is UV present. Does the animal utilize and rely on all of the display functions or are only some of them sufficient?

 

[Miagic Mike]

yes, they are fascinating animals.

Another day another lot of photos! stay tuned for tomorrow>>>>>>>>
