Summary
Engineered microorganisms produced solitary bee silk proteins that researchers purified into transparent, freestanding films—the first time this kind of bee silk has been made in the lab and turned into a material.
A 3D-printed rearing system let the team collect fibers directly from blue orchard bee larvae as spinning began, preserving cocoon formation and giving them a minimally invasive way to study the silk.
Blue orchard bee cocoons are puncture-resistant, flexible, antimicrobial and breathable, properties that could suit surgical sutures, tissue-engineering scaffolds and technical textiles once the material is developed further.
About 75% of bee species spin silk, and the team says the method could be extended to other bee silks—or blended with materials such as hagfish slime—to create biodegradable alternatives to plastics.
Bee silk and hagfish slime: are we on the verge of creating nature-inspired hybrid super-materials?
Can lab-grown bee silk scale up to truly challenge the massive global plastics industry?
Solitary Bee Silk Breakthrough: First Recombinant Production and Transparent Films Open New Era for Tunable Biomaterials (2026)
Overview
Solitary bees spin silk fibers to build protective cocoons, giving their offspring a strong and safe environment. In July 2026, scientists at Utah State University, led by Oran Wasserman and Justin Jones, achieved a major breakthrough by successfully recreating solitary bee silk in the lab and casting it into transparent films. This marks the first time a solitary bee silk protein has been produced and processed as a usable biomaterial. This foundational achievement opens the door to new research and applications, as the ability to make solitary bee silk proteins in the lab paves the way for developing tunable biomaterials with unique properties.
