Oh interesting. Okay, this needs to go to the devs, actually. Thank you very much!
Hi teawolf, so remembered this and realized it kind of disappeared again - but recently read the Suck and Ride scene again - it doesn't state fertilized one way or another. But reading the codex again - all Vesparan females are rendered sterile by a pheromone the Queen produces so they shouldn't have any eggs fertilized or otherwise unless the queen specifically gives them to them. So both scenes should be a guaranteed vesparan pregnancy - Also based on the codex the actual pregnancy is 10-12 days - which should be the full pregnancy mode duration if it's in the codex, but according to the wiki (which could be wrong, correct me if it is) that's the short pregnancy duration while the long is like 60 days which is ridiculous as it's not lore accurate. Since the normal pregnancy is only 12 days I feel like vesparan pregnancies should be 12 days regardless of pregnancy mode. Figured I'd bring that forward too since you'd be dealing with those anyways.
So TL: DR - Based on Lore any egging scene from Azzy (and any other hornet besides the Queen) should cause a versparan pregnancy, any language about unfertilized eggs should be removed from either scene if there, and the vesparan pregnancy should be 12 days long for full pregnancy mode, while short pregnancy mode should be the same length or shorter.
