A large pot nest built by a potter wasp. This nest is old and empty as the larva has already matured and abandoned the nest. The material used for building this nest are decomposed wood, containing a bite of mycelium from decaying fungi. This pear-shaped nest have branched out spikes at the entrance of the nest which looks like a star but unfortunately some parts were broken. The mother wasp has also added lines / ridges running vertically down the nest for extra structural support. She is indeed a great architect. I saw plenty other nests around this area, on walls usually up high. Possibly a Eustenogaster calyptodoma.
