Having lived in England, I am conscious of the amount and variety of bugs we have in Durban, especially in summer. But this one in particular caught my attention. I was sitting in my lounge one night and heard an unusual whining sound, like that of an animal. I looked around the house for the source of the sound and eventually found this large, luminous green insect, and manage to snap a few pics. Has anyone come across this bug and heard the weird noise it makes?
