Micrathena sagittata (female)

Aka Arrowshaped Micrathena. My Dad had actually pointed this one out and it's a good thing to, because I probably would've never noticed it. Also this is the very first time I've ever seen these in person (up til now I've only seen them in books.) I'm not sure what it was feeding on though, but I suspect it's either a conspecific or an insect that it caught in its web.
