I lost another 2 caterpillars today, this time from the second cohort (~3rd instar). A spider attacked them between when I checked this morning and when I looked this afternoon.
1st cohort - 5
2nd cohort - 6
Eggs - 5
This is what the eggs look like today:
The darker ont near the top is one day older. It looks like it is about to hatch - maybe even tomorrow.
