Also, why don't you go ahead and post the other images you have of the egg... let's take a look at what else you've got!

The caterpillar from the new egg died yesterday. Those photos therefore won't produce a complete life-history set. I can post them anyway if that's desirable. At least the color change in the egg is informative.

The caterpillar was doing well until recently. Early last evening, it fell off the parsley onto the horizontal surface of the bottle top (I have photos of the apparatus--not posted, as this setup didn't make for a successful rearing). This was a drop of about an inch. I put it back on the parsley. It was moving slightly then. It was dead a few hours later. I now think these caterpillars may be incubating a disease from the beginning. We used all different apparatus for this latest specimen, making sure the container was well ventilated and not humid. The page at http://tinyurl.com/njqw23 describes a disease of two other butterfly species. If the mother carries this disease, the offspring gets infected when it eats the eggshell. That disease and the species are different, but perhaps anise swallowtails have something similar.

When people write that you mustn't have open water because larvae fall in and drown, I now think that maybe those larvae fell because they were ill and weak, and a healthy one will hold on.

It was the same specimen. I didn't see the egg hatch, but I marked its location by hanging a small piece of colored wire lower on the stem. The hatchling first appeared in the same place, four days (the known incubation interval, according to a comment on someone else's image page) after I'd noticed the egg. Admittedly, I didn't stay out there all night and watch.

I've added a photo from July 2 and linked all three. Getting them in sequence took a while to figure out.

The other photos belong in a different series. They show another egg, which I brought into the house after the three first- and second-instars vanished at the same time. I had even tried to protect the one on this page by building a cheesecloth shelter above and around its carrot stem. Probably the wasp got in from below. I don't know how far the development of the larva from the second egg will proceed. It may not yield a full life-history set of photos. We haven't yet kept one alive past the third-instar stage. I suspect illness--there's more about this in Forums.

I'll post as time permits. There are so many bugs out there! And some in here!

And this is the busy season for editors--I'm saving up photos of yet other creatures to post in winter--and bugguide may have better photos of this species' life stages anyway.

That egg hatched. Anise swallowtail. It got as far as a molt, July 10:

A few days after that, I believe a wasp got it as well as two smaller ones in the same bed. So frass unless there's value in showing what that species' egg looks like.

I have other egg photos, not yet posted. One shows the color shortly before hatching.

...as discussed in this other post from this contributor.

that was a useful discussion
