This is probably one of the earliest videos I took way back in my Perungudi home that I just uploaded on to YouTube. Searching on YouTube I found one other video called Queen Hornet’s hive. So I am not sure if it was a wasp or a hornet that built this very weird looking nest/hive on the grille of my window. Here’s the video.
Let me see if I can locate the pic of the insect that built this and will post it soon.
