This is how I had it glued. If I were smart, I would have taken note of the rather obvious

This is how I remounted it 4 days later, using the original groove, and a stick that fit it perfectly:

Most of a typical ooth is just random foam bubbles, sometimes somewhat striped. Somewhere directly opposite where the ooth was attached, there should be a line of things that does not look random, looks different, more planned. It might look like zigzag lines (zipper), it might look like stacked shingles or a louver, it might look scales, it might look like a stripe of foam different from the rest, etc. If we use the example of stacked shingles (like with Chinese), the gap between each of them represents a tier of 1 or many eggs and the babies come out of that gap. In the instance of the Chinese mantis, there are about 10 eggs per tier and several/many tiers per ooth.

Do a Google image search for 'mantis egg case' and you should find some pics of 'zippers' and of ooths hatching:

On that second photo, what is that white stuff that looks like foam?

Is it hatching?
