勺翅草蛉 Nemoptera sinuata 的口器适合摄取花粉和花蜜。描述了口器的形式和功能，并结合赏花行为和首选花朵的花型结构讨论了食物摄取技术。上颌骨是摄取食物的主要器官。刷状的唇纹、帽状腱膜和上颌须形成一个功能单位，可以通过心柄关节的作用而伸展。对口器运动的视频分析区分了花蜜进食或花粉采集时发生的上颌运动的不同模式。神经翅目的探花行为和特殊的口器可能是从神经翅目中的掠食性和咬/咀嚼口器进化而来的。
The mouthparts of the spoon-winged lacewing Nemoptera sinuata are adapted for the uptake of pollen and nectar. Form and function of the mouthparts are described, and the technique of food uptake is discussed in context with flower-visiting behaviour and floral architecture of the preferred flowers. The maxillae are the main organs for food uptake. The brush-shaped laciniae, galeae and maxillary palpi form a functional unit which can be extended by the action of the cardo-stipes joint. Video analyses of the mouthpart movements distinguished different patterns of maxillary motions which occur in nectar feeding or pollen collecting. The flower-visiting behaviour and the specialised mouthparts of the Nemopteridae are derived traits which probably evolved from predatory and biting/chewing mouthparts within the Neuroptera.
