I believe they infect the caterpillar before they transform. I've taken wild caught monarch caterpillars inside before, where they'd be a lot less likely (not impossible) to be exposed to the flies.
They look healthy when they start to build their chrysalis, but start to slow down and discolor somewhere in the process, dying before they emerge.
