Not too much happening here. Fast forward to see the closest two show-off their wings.
These adults are very reminiscent of the larvae. You can see them still eating from the initial pile because the larvae and the adult both eat aphids (you can see a little scuffle there at about 10:30).
***10 of the 12 have emerged. The final two should emerge by the time they are released. They both went into their pupa at the final same time.
