Saw this encounter today in Taroko:
1 medium sized maybe Giant Wood Splider (
Nephila maculata), black and yellow markings, but not as big as others I've seen.

Buzzing around the web, attacking whatever the spider was protecting was a hornet. It didn't give up, and I watched for a good 10 minutes. Everytime it flew in, the spider fought it off with aggressive pincer movements of its front legs. Then the hornet would fly higher, and try another angle, or lazily pretend to fly off only to come in again. The spider would edge round its 'treasure' to defend the other side.
