On Sunday night (5 days ago), a moth laid a bunch of eggs on the outside of our kitchen window (video and pictures here), and late this afternoon, the eggs hatched. Here's a picture of the wee beasties shortly after they hatched, courtesy of Paul and his camera's awesome macro mode:
These little creatures are each about a millimeter (ONE millimeter!) long, and there are just so many of them. Here's a super-zoomed-in view of the above picture, where you can even see their tiny little legs:
I have no idea what these caterpillars are going to do next -- there are no plants nearby, which is usually the case when you're in the middle of a window pane. The only thing I can think of is that they might eat each other, and maybe that'll get them big enough to go exploring (many, many feet) and find a suitable plant to munch on.... Who knows! I'll keep an eye on them and see what happens. Nature sure is crazy sometimes!
