Hang on there
If these parasitic bees infest a hive and lay eggs to overtake from within like some slightly less gruesome face-hugger of renown, do the dirty worker bees still work, or do they just lounge around pretending to be queen bees and quaffing all the royal jelly ?
Because if they don't actually work and cannot do anything more than produce more parasitic offspring, then they are the terminal race for bees since, once all behives have been infested, there will be no more bees to do the actual job and they will then die off.
So they are the Umbrella Corp of bee-land.
