Silkworm Availability Update

We're currently in the middle of our next production cycle, with over 200,000 silkworms hatching and growing. During this transition, some sizes may be more limited than usual as we allow them to reach the quality and size standards we expect before shipping.

You may notice that some silkworms arrive on the smaller end of their listed size range. To help them continue growing after arrival, we're including free fresh mulberry leaves with eligible orders so they'll have plenty of food to reach their full size quickly.

Over the next couple of weeks, our inventory and sizing will continue to improve as this next generation matures. In the meantime, we'll do our best to fill every order we receive. To ensure our long-term customers have a consistent feeder source, weekly and biweekly subscription orders will receive priority when inventory is limited.

We truly appreciate your patience and understanding during this brief transition. Thank you for your continued support—we'll be back to our full selection of healthy, high-quality silkworms very soon!
