Rigid threads: Lacewings protect their eggs from predators by laying them on small stalks (see picture). The stalks have good mechanical properties and, unlike most other silks, a cross β structure. An artificial egg stalk was produced using a designed recombinant variant of a sequenced lacewing egg stalk protein, and it attained 90 % of the tensile strength of a natural egg stalk.
草蛉通过将卵产在小梗上（见图）来保护它们的卵免受捕食者侵害。这些小梗具有良好的机械性能，并且与大多数其他丝不同，具有交叉 β 结构。使用经过测序的草蛉卵梗蛋白的设计重组变体来生产人工卵梗，其达到了天然卵梗拉伸强度的 90%。
