Ditto here, plus typical twisting, and size of larva.

These past two years I've seen sick larvae of all kinds of color (lots
of yellows throughout the body), smells, twisting, sacking, etc.

PCR has found SBV, BQCV, and a bit of AFB (but no clinical signs).  I
also suspect other viruses, esp since there appear to be multiple
spikes under IVDS analysis (thanks to Dr Bromenshenk).
