Wasp nest!

Of late I've been wondering why dead caterpillars have been showing up at my doorstep. Today I found out why. There was a brownish looking mound on top of my door frame and it turned out that it was indeed a wasp nest. The dead caterpillars was a result of it. I only realised it when I came back after lesson and saw to my chagrin an adult wasp on top of it.

A quick call to Siew Teng was the result and he came down, efficient as he is, to take a look at it. A few hours later one of the cleaner (the very nice uncle) came to remove it. After removing he told me he saw a few 'green worms' inside and I finally realised the source of all these caterpillars! :P
