The green lacewing Ceraeochrysa smithi (Neuroptera, Chrysopidae), like other members of its family, lays its eggs on stalks, but it is unusual in that it coats these stalks with droplets of an oily fluid. The liquid consists of a mixture of fatty acids, an ester, and a series of straight-chain aldehydes. Relative to the eggs of a congeneric chrysopid that lacks stalk fluid, the eggs of C. smithi proved well protected against ants. Components of the fluid, in an assay with a cockroach, proved potently irritant. Following emergence from the egg, C. smithi larvae imbibe the stalk fluid, thereby possibly deriving nutritive benefit, defensive advantage, or both.
绿草蛉Ceraeochrysa smithi（脉翅目，草蛉科）与该科的其他成员一样，将卵产在柄上，但不同寻常的是，它会在这些柄上涂上油性液体小滴。这种液体由脂肪酸、一种酯和一系列直链醛混合而成。相对于缺乏柄液的同属草蛉的卵，史密斯草蛉的卵被证明能很好地抵御蚂蚁。在对蟑螂的试验中，这种液体的成分被证明具有强烈的刺激性。从卵中孵化出来后，史密斯草蛉幼虫会吸收柄液，从而可能获得营养益处、防御优势，或两者兼得。
