Yesterday I noticed a small spider in our greenhouse. I was fascinated to see it tracking a fungus gnat on the window pane, and very surprised when it jumped and caught the gnat for a quick lunch. Because I suspected it would grow into a bigger spider that I wouldn't want to deal with later on, and not wanting to walk through webs in my work space, I caught the little critter in a pail and took it out into the sunshine where it ran and hid in some rocks.
Turns out it was a Zebra Jumping Spider that doesn't grow any larger than it already was, spins webs only as safety lines, and hunts for prey by crawling around. So the little Zebra and I could have happily coexisted in the greenhouse for the most part, at least until she decided to leave an egg sac behind. I don't really want an overpopulation of Zebra Spiders in the greenhouse, but now I may end up with an overpopulation of gnats. Oh well, they're part of the ecosystem too, somehow.
