From what I understand, these new diapausing spider silk strains are designed to stabilize and streamline production output by introducing cold-storage flexibility into Kraig Labs’ silk production cycle.
In the current non-diapausing system, the process looks something like this:
eggs hatch > larvae grow > some spin silk, others mature > mate > lay new eggs > repeat.
But this creates natural pauses in the cycle while waiting for new eggs to be produced — and limits production to just 8–9 batches a year.
With diapause-capable strains, Kraig can now pause egg development for up to 90 days in cold storage, giving them the ability to bank eggs ahead of time and then “wake” them on demand. This means there's no longer a forced downtime between batches, because they always have viable eggs ready to hatch and rear when needed.
The real breakthrough is that this allows them to stagger and scale operations across two parallel facilities:
One facility focuses on parent strain growth and egg production, putting fertilized eggs into diapause (cold storage).
The other pulls from previously stored eggs to maintain continuous silk production.
By rotating and overlapping these roles, Kraig can maintain a predictable, year-round supply of silkworms, eliminate production gaps, and boost total throughput — all while improving silk quality and meeting higher-grade market standards like the one set by their European fashion client.
So this isn’t a pause or slowdown — it’s a strategic infrastructure upgrade that brings them in line with premium silk production models, and sets the stage for true industrial-scale spider silk manufacturing.
So here's hoping it all works out. It sounds like something they needed to do, if I had to equate it to something, it's like artificial pollination for fruit year-round. Instead of waiting for the "in-season" window, they can now control the entire cycle and generate output all year.
