And, yes, it is catching bugs.

I discovered that, if I completely fill the pitchers with a hydroponic fertilizer solution, 6 g./gal., the pitchers will absorb it, until about half full, within 3 days. Apparently, the pitchers absorb water as efficiently as roots.

Elsewhere, I discussed the feasibility of foliar feeding calcium and, theoretically, it is not feasible because calcium doesn't travel down the phloem. Maybe, the nepenthes pitcher plant is an exception because it could have evolved to absorb the digested bones of small vertebrates such as tree frogs.
