Advertisement I don't have pics atm because I'm not home but I was thinking. I've seen adult male regal jumpers before and almost all of then have white on the backs of their heads and very bright and fluffy tufts of white hair on their front legs. Mine does, but it's not very brightly coloured. He has no white on the back of his head. He has eaten to the point where his abdomen is about a millimetre wider than his head in diameter. Can a male jumping spider have swollen pedipalps if he still has one more moult to go? I've never seen a fat male jumper so yeah I can provide pics later if necessary but I think I described him pretty well. He basically looks like a female phidippus audax with way less hair and a much larger head and chelicerae.
