I had the same thought as Malcolm. I had A. junius metamorphose in 120 ml cups of water; just make sure they have good sturdy twigs to climb out on (some tried hanging on to the sides of the cup and ending up falling off and failing to emerge completely). Definitely avoid group-housing them.
The nymphs must occur at much higher densities than the adults in the field, due to the limited space of the aquatic environment versus the open air and the numbers that are predated as adults. Also easier to catch and much less delicate. If you decide to go the shotgun route, I insist you make a video of this and share it with us ...
