Black Swallowtail chrysalises not hatching...
by Lela Roy
I have 6 Black Swallowtail chrysalises that pupated in late June. It is now September and none of them have hatched. I was worried that they were dead but I saw one of them move today and now I am just confused as to why they have not hatched yet? They have been kept pretty warm so I don't really see why they would be trying to overwinter.
Does anybody have an approximate time estimation it usually takes for them to hatch? What should I do with them at this point? I have no idea!
That seems like a very long time. The black swallowtail's time to emerge varies quite a bit in my experience. I would say generally they emerge between 2 to 3 weeks (except those that overwinter). As far as what you should do....you could just leave them or put them in a colder place until spring and then bring them inside.
