Brown Huntsman Spider

I've just read the info below on wikipedia and am now wondering if this is what this spider was doing. He was anchored to the wall (see 4th photo) and was sometimes 'waving' his front legs about...

"Males of Heteropoda venatoria, one of the huntsman spiders that seems to easily find its way around the world, have recently been found to deliberately make a substrate-borne sound when they detect a chemical (pheromone) left by a nearby female of their species. The males anchor themselves firmly to the surface onto which they have crawled and then use their legs to transmit vibrations from their bodies to the surface. Most of the sound emitted is produced by strong vibrations of the abdomen. The characteristic frequency of vibration and the pattern of bursts of sound identify them to females of their species, who will approach if they are interested in mating."

You're right! I've just noticed! :-}

Lovely! Poor spider is missing one leg....
