I got tired of waiting and harvested my teeny-tiny Brussels Sprouts - chopped... sawed the stalk off, brought it in, started cutting off the sprouts (which were tasty, but not taking up a square for 10 months tasty...clearly I'm not doing something right...) and at the top of the stalk I found weird fuzzy yellow eggs - or at least I thought they were eggs, because why would cocoons be in a cluster? Either way I didn't want anything hatching inside and took a pic and put them back outside with the stalk.
Here's the photo. That's the corner of a bottle-cap for scale in the upper left.

After some searching I think these are the cocoons of a braconid wasp that feeds on cabbage worms.
Like this, but with the caterpillar 'husk' having fallen away:

Neither the cabbage butterfly caterpillars nor the wasps should be inside the Agribon covered beds... but stuff happens.
So the "why would a bunch of cocoons all be in the same place?" is because the larvae that made them all originated from inside the same caterpillar.
If you see similar clusters of fuzzy business on your brassica plants, you may wish to leave them so that they can hatch into more parasitic wasps.
