Australian Creepy-Crawlies of the Redback Variety

So I've finally had a chance to see some of the things I shouldn't touch while in Australia! I went out for lunch on Sunday with a family from church, and after lunch as we were touring the yard they mentioned having noticed a redback spider a few days ago and and eagerly took me to see it where I managed to get a picture of a male and female pair (though they don't normally spend time this close together, that's an artifact of us disturbing them).

The large one on the right is a female, the smaller one is a male. Note the distinctive red stripe.

Redback spiders are in the genus Latrodectus, the widow spiders, to which the black widows I grew up with in California also belong. As such, they show very similar behavior, weaving stringy, chaotic-looking webs and being ambush predators, not being very aggressive, and generally only coming into contact with humans by accident. From what I've read their bites (of the females, specifically), although very painful, are hardly ever fatal. So that's reassuring, I guess. A hui hou!
