Butterworms are shipped in wheat bran, for bedding material and to absorb moisture. The Butterworm may eat a little while stored. They can be stored in the refrigerator at temperatures of 38-42 degrees F. Butterworms can be stored in the refrigerator for 1 to 2 months with minimal loss. Butterworms are a little more expensive than Silkworms BUT they have the advantage of being able to be stored for extended periods of time in the refrigerator.
