Question Microscopic Wasp

While i was in the Wombat State Forest on the 27/3/22 i saw this little black object on a gum leaf . Initially i thought it was a piece of dirt but then it moved so i got it and the leaf in a container . When i got it home i saw it was a tiny wasp , it is less than 1/2 a mm wide and not quite 2mm long , it also has strange bulges on its thorax near it's wings . I haven't been able to identify it yet .
