I was completely exhausted at the height of the feeding
Nicki, you need to recruit people. Here's what I find successful:
Early in the season, give your target a fat and healthy 5th instar, preferably one that you raised from an egg, so no tachnid fly. And milkweed of course.
In 10 to 14 days, you'll get a call or e-mail: "OMG!! It was so great!!!"
But don't reel them in just yet. During your mid-season, say that you're going on vacation and need someone to take care of a few -- maybe 3rds or 4ths. It will still be a cool, not exhausting, activity for them.
When those B's have been released, they will probably ask for more, or mention that they want to grow milkweed. THEN you reel 'em in, just in time for the height of the season.
Two of my recruits now surpass me in number of B's released every year.
