Silver,
I had asked for your no. 2 and no. 3 picks which you omitted - not insect stages, but thanks.
See second definition:
Definition of Emergent:
e?mer?gent (-m?rjnt)adj.1.a. Coming into view, existence, or notice: emergent spring shoots; an emergent political leader.
b. Emerging: emergent nations.
2. Rising above a surrounding medium, especially a fluid.
PS There is also a later stage. Even the fly which is totally out of the shuck is still a subimago. It is not until they molt again; become sexually mature, that they reach the Spinner stage.
So, I still need your #2 and #3?
Thanks,
Byron
