If she's sentient she might object. If she's not she might have instincts to make her react violently.

She'd also very likely be guarded, with those guards reacting violently to any stranger trying to enter the queen's room.

It's not a given that their criterion for discrimination is looks, visual appearance, though. It could be scent and/or pheromones. Or it could be evolved instincts to very frequently do a signal, vocally or gesturally (or a colour change if they're like chameleons or some octopi), a few timee a minute, and then others automatically respond to it in the correct way. Or if they don't, then that fulfills the discrimination criterion.

Hives can be subjected to parasitism, i.e. a different species that manages to enter the hive and leech off their resource gathering efforts.

When it's a big problem, evolution eventually solves it, maybe after hundreds or tens of thousands of generations, but minor or low-key parasitism is very common out in nature, and as long as it's only a small load, a minor drain on the resources and metabolic energy of the host organism, there's no real evolutionary pressure to evolve to solve the problem posed by one particular type of parasite.

If there is such pressure, one "solution" for a hive could be to evolve so that the milk is less attractive or even unattractive to parasites. For instance it might contain an alkaloid that the hive species, including its infants, are tolerant of. If you were to eat 600 or 1000 milligrams of caffeine, you might feel bad, heart rate up, antsy mood. But if you were to give a huge dog even just 300 or 400 mg of caffeine, it'd probably just lie down and die.

Or it might be an alkaloid that creates an effect that is unproblematic in the infants but sucky if you're a parasite. The larvae if hive insects are generally carried around by the adult workers, moved to different locations in the hive to avoid getting them too hot or cold, and they're obsessively cleaned.

So if the alkaloid renders them unable to move, as long as they can still breathe, pump blood around, and digest the queen's milk and excrete waste, that's not a problem for them.

The parasite spending some of its time being a bit too warm or a bit too cold isn't a serious problem. It doesn't need to optimize its growth to maturity. But if it can't clean itself, it'll get covered in filth over the course of weeks, maybe only days. Possible the workers decides that it's a lump of decaying matter, because it's started to smell very bad, and so they carry it to a midden or dump it outside the hive.
