I found this guy in a patch of wilderness in Bangalore, India. He was flying around, carrying little rocks to his little hole in the ground. I was wondering what bug this was? I was a little afraid to get too close, because I wasn’t sure if that was a stinger at the end of his body. I’m uploading two pictures, since only one of them properly shows his abdomen.
We apologize for not having the time to hunt out the species for this wasp, but we are relatively certain it is a Thread-Waisted Wasp in the family Sphecidae. This series from BugGuide would support our speculation. Perhaps your female Sphecid Wasp is beginning to seal this nursery burrow.
