Post Color Change in BSFL
I know that when the BSFL crawl off to pupate, they are generally dark in color. My question is, what causes the color change, and is is gradual, or can it be immediate? Yesterday when I looked in my bin, there were very few dark BSFL, and today, I had a massive crawl-off with lots of darker grubs. Can this happen overnight?

I recall reading that when BSFL are ready to pupate, they purge their gut and secrete some kind of enzyme. My guess has always been that the enzyme serves to toughen up the carapace a bit, to give them a little better armor, moisture retention, and camouflage for their journey.

Where is the frass? Are the other grubs eating it?
