greater banded hornet attacking wasp nest

This is a follow-up spotting to one four days ago in which a single hornet was casually eating Polistes sp. larvae with impunity, as the adult wasps stood idly by, semingly oblivious. That spotting is here http://www.projectnoah.org/spottings/18262067 This evening's visit of the hornet was markedly different. The single hornet was vigorously tearing apart the nest cells to get at the larvae. The crunching sound of this was quite audible. The wasps still did nothing. This attack took place at near sunset. Also note the several eggs are visible in the series.
