I took a brief blogcation this weekend, travelling to New Orleans for my sister’s wedding, and I missed posting the Sunday Night Movie. I hope to make it up to you with the best spider in the entire galaxy:
Things really get going around the 3 minute mark.

Great, but the photographer and source deserve some acknowledgement.
Indeed. It comes from Jurgen Otto, who also has a stellar set of still photos.
The way the iridescent green patch changed to black at certain angles — has anyone checked for interesting polarization or UV reflectance/fluorescence signaling in this species?
It’s been found in other spiders– for example:
Lim et al. 2007. “Sex-Specific UV and Fluorescence Signals in Jumping Spiders”
http://www.sciencemag.org/content/315/5811/481.short
Not sure if there’s been research done on spiders signaling with polarized light, but some groups can see it:
Dacke et al. 2001. “Polarized light detection in spiders”

Congrats to your sister!
Did I miss see the last male who was successful or was he missing a pedipalp?
The males getting caught and eaten reminds me of one of undergraduate projects describing the courtship dances of two species of Zygoballus (Araneae: Salticidae). I miss matched a male and female and when I introduced the male into the female’s arena, he pierced her pretty cephalothorax. I tried to continue working but I was so upset, I had to quit for the day. I still have a vivid memory of that shock.
Impressive spiders, I’ve been reading a bit about these lately – a friend of mine from Berkeley is going to Australia to study these soon!

Oh, man, they are sooo adorable!
That’s a really nice video… and I almost missed it! I need to stop letting work and the rest of my life get in the way of my blog reading.
