This reminds me of a time I was looking for woodlouse (y'know, pill bugs. They roll up into little balls) and when I picked one up and unrolled it, a
big spider popped out and it looked freaking scary.
But I can think of two things: The fly was infected with a parasite from a larger wasp, a wasp larvae. Of course, most wasps are larger than the fly,
and so would their grubby little worms. Wasps have a thing with that, infecting caterpillars, but in desperate times, they have been known to go off
Then there's the fly was pregnant with an unusually large larvae, which is unlikely because that would be one monster fly and flies lay eggs, up to
like fifty at a time or somehting like that.
