Here is a Home Depot rescue from way back, a now four-foot female blooming vine of Nepenthes x ventrata, which has a penchant for attracting bees -- far outstripping that of the other "windowsill" Nepenthes. The subject in the photos lapped away at nectar for a couple of minutes, performed a strange "waggle" dance, climbed onto the peristome, lid, and fell "abdomen-backwards" into the pitcher. It was still struggling when I uploaded the picture.
