web master or web mistress

The Original Web Master (or Web Mistress)?

This webmaster has the tools.  Look at that fat little ... is it a web mistress?  This is a European Cross Spider.  We see them every year in Washington state.  Can anybody tell me how you tell a male from a female spider?  I have no idea.  I've been assuming that this is a chubby little boy spider.

Here's a closeup of the underside of this same spider.  Are there standard webmaster guidelines for telling  whether this is male or female spider?  Where's an insect expert when you need one.  I think spiders are like boys and girls, but its crawlers like this that make the internet is a less safe environment for carnivorous insects.

This third photo is not the same spider, but another spider of the same species that was in our backyard.  

Here the webmaster enjoys the spoils of the bounty!  Har, mateys! When a spider eats it must first liquidate its food with enzymes.  Sometimes spiders are poisonous too!  Yo ho ho!  Spiders are kind of like pirates.  They live a life of hunting and killing.
