I don't think this photo needs any comment - but just in case, it is something I've never seen before, in fifteen years of country living and gardening. In fact, this is something that I'd have sworn was impossible: a slug descending from a tree, spider-like, on a string of its own mucus. It may have been an GMO slug, some sort of arachnid-gastropod determined to shun the beer and the eggshell traps I'd set for it in my cabbage patch, by parachuting directly down onto a tasty cabbage leaf. I don't know for sure. But I can tell you what I heard quite distinctly as it dangled down right in front of my nose: slug laughter!
(Full disclosure: I very much appreciate your tips on how to fight garden slugs, which I'm implementing right now. In reality, the spider-slug, clever though it was, hadn't actually found my garden yet: I encountered it in the woods, where it descended from a tree to peek into the basket of pine cones we were collecting).
