Real Spider under Phal's leaf!

[CourtneyT]

Yesterday when I was checking my phalaenopsis, I saw some webs in the pot. My first thought was that it got spider mites! After checking the plant, I saw a Real, Big Spider making web under the leaf! What should I do now? Repot it or leave it alone? Or just get rid of the spider and the web? I didn't see any damage to the plant yet. This pot is currently holding two phals and the other phal. just started to grow a flower spike. Also, is the spider nesting there a sign of too much humidity and slow air flow? Since the home is pretty cool (59F to 65F) and outside is about 20s to 50s, I haven't really opened the window this winter.

Well, at least I'm not scared of bugs so I didn't scream. I'm just worried about my plants.
