Had bad experiences with sand fly bites while living in Darwin. Didn't know I was bitten but had multiple blisters up to 5-6mm with a clear fluid. After a day or two they would break and then bleed....
Yes, Black flies have a very powerful bite, with the power close to the power of a male lion, these bites crush bones and poison the body killing within minutes.
