Okay, I'm a new voice in this discussion, and I'm surprised no one has said what it is I have to say. The IP editor above got quite close.

It's not actually a very complicated case: Osgood is an identity. The whole point of her character in the Zygon two-parter is that once both assumed that identity, neither was specifically human and neither was specifically Zygon. If we must put something in the infobox as species, Osgood literally gives us "hybrid" in the script.

So. Osgood is Osgood, regardless of origins. It is an identity, and it is a character. Prior to TDOTD, that identity belonged to only one individual. So in the history section of the one Osgood page, it would, at first, simply be human Osgood's story. Prior to to the peace treaty Day, "Zygon Osgood", as we seem to be calling her here, did not identify as Osgood. Prior to the end of Inversion, Bonnie did not identify as Osgood.

Thus, the Osgood Zygon from Day still needs their own page, but their history ends when they actually become Osgood, and Osgood's joint history continues on the Osgood page. The Zygon who mocked Osgood, stole her inhaler, who I believe tried to attack Clara, is not Osgood. That Zygon, though, slightly later on in their history, became Osgood, and at that point it all merges. No duplicate information needed on the Zygon page, because that individual ceased to be that Zygon that was impersonating Osgood, and became one of two Osgoods, each with a different species.
 * Let's call that page Zygon (Osgood) for now, because I think some unconventional dabbing for this case is in order. That character is a Zygon, and not actually Osgood; "Osgood" is simply the only identifier we have for that Zygon, because that was the form they took and no other name was revealed. Zygon Kate Stewart should be Zygon (Kate Stewart) as well, Zygon (Elizabeth), Zygon (horse), etc. In normal circumstances, the disambiguation would be the story page, but in this case there are several Zygons from the same story that each need individual pages. (On a slightly off-topic note, I think we should do the same with Slitheen whose actual names we don't know—Slitheen (Human They're Impersonating) 
 * I think it's a very different case with Zygons than it was with Gangers, who were the people they were copied from, simply not human. These Zygons were simply Zygons who we characterise by the people they pretended to be. If we ever do find out which Osgood is which, which I believe we won't, and we decide to separate them, then they would get Ganger-like treatment, with Osgood as the main name, and, say, (Zygon) and (Bonnie) as disambiguation terms.

Though obviously we can point out that immediately after the merge, each knew which they were because Zygon Osgood gave human Osgood her inhaler, unless something new comes up in future, we should not attempt to separate Osgood by her species at any point after the inhaler scene. We can only state that Osgood knew which species she belonged to, and treat all self-identifying Osgoods as one identity, which no distinctions made except that there were more than one. "One of the Osgoods..." "Osgood told the Doctor..." "The Osgoods worked together to..."

They have a shared identity. Why does everybody feel so strongly that she must be separated, when clearly what Osgood wants is to be considered collectively, and as simply Osgood, regardless of her species. Attempting to make divisions where no divisions actually exist in her identity would be akin to trying to shove real-world non-binary people into a binary gender, just because you feel they must be assigned one. It was actually kind of rude for the Doctor to be continually asking her, because why should it matter? She is Osgood.

Anyway, in the same vein, Bonnie (The Zygon Invasion), who does have a name of her own, would be the same. She'd have her own page, her own history, leading up to her taking the identity of Osgood, at which point she would simply be Osgood, and would be part of the joint history from then on. So Bonnie's infobox picture would be of her in Clara's form, or maybe in Zygon and Clara form. At the end of her biography, she ceases to be Bonnie at all and becomes Osgood. Simple. Her personality is her personality as Bonnie, while she was identifying as such, just like the Sixth Doctor's personality section is that incarnation's personality and not the following Doctor's. She effectively becomes a different person in the same manner.

Of course, if there weren't three potential individuals melded into one identity, and Bonnie was the only surviving Osgood, Bonnie's page would just have an "As Osgood" section. This is not the case we are dealing with, though, and I believe the solution is clear. Once again: one central Osgood (The Day of the Doctor) (we can't actually say we know her first name at this point, because we don't believe the Doctor on "Basil", and she called him that when he called her "Petronella" at the end of Inversion), and pages as well for Zygon (Osgood), the one who impersonates Osgood and steals her inhaler, and Bonnie (The Zygon Invasion), the one who impersonates Clara and leads the revolution. At one point, those two were separate entities from Osgood, and those pages would cover those lives, as effectively ending when they each become Osgood.

In timeline format: Et voilà!
 * 1)  Joining UNIT—before Human-Zygon treaty (1 Osgood): There is one Osgood (The Day of the Doctor). She is human and works for UNIT.
 * 2)  Start of Operation Double—'s arrival (1 Osgood + Zygon = 2 Osgoods): Zygon (Osgood) becomes Osgood, and there are two Osgoods.
 * 3)  Missy's murder—Zygon rebellion (2 Osgoods - 1 Osgood): Missy kills one of the Osgoods, and the remaining Osgood does not identify as either human or Zygon specifically, refusing to tell anyone what her species is.
 * 4)  Rebellion steps down—present time (1 Osgood + Bonnie = 2 Osgoods): Bonnie (The Zygon Invasion) becomes an Osgood, and there are two Osgoods again, at least one of which is a Zygon. Both of which are Osgood, just like the one who had died.
