Forecasted Milestone Timeline

Chronological lifecycle markers for Zebra Swallowtail

1
Ovum Collection / Laid
Day 0Sat, Oct 17

The host leaf cutting sits in a fresh aquapic in shaded mesh, misted lightly when ambient humidity falls below 40%.

2
Estimated Hatch (1st Instar)
~Day 5Thu, Oct 22

The neonate eats its eggshell first, then moves to tender young host leaves. It is not handled at this size: the cuticle tears.

3
Mid-Larval Molt (3rd Instar)
~Day 12Thu, Oct 29

Appetite accelerates, and so does frass volume. Daily frass removal and a morning change of wilted foliage is the usual routine.

4
Peak 5th Instar Feeding
~Day 18Wed, Nov 4

Most of a caterpillar's lifetime food intake happens in this stretch, on fresh chemical-free host stems replaced daily.

5
Pupation / Chrysalis Formation
~Day 21Sat, Nov 7

Pre-pupal wander phase (Girdle / Twig Sling). The silk pad is spun, and the shell takes about 48 hours to harden; an undisturbed enclosure is what that needs.

6
Wing Pigmentation Visible
~Day 34Fri, Nov 20

The chrysalis turns clear and wing patterns show through the chitin. Eclosion follows within 12–24 hours.

7
Adult Imago Eclosion & Release
~Day 35Sat, Nov 21

Emerges with crumpled wings and hangs downward 2–4 hours to pump hemolymph. Releases are generally done in warm sunshine above 65°F, near nectar flora.
