You can tell on Monarchs if it is a boy or a girl while in it’s chrysalis. You can tell on an Eastern Black Swallowtails too, but the chrysalis looks different and I don’t have pictures of that yet.
On the back side of the chrysalis, there is an indented line between the black dots. If you look a little further down there are stripes underneath. If you look really close–you have to have good eyes– there is a line by the stripes. If you see the line and it does not touch the stripes, it is a girl. It is much harder to to see the line touching for the boys, it looks like there is nothing there, unless they emerged and you have a microscope.
Well the pigtails did not show up!
Well done for all you are learning.
