Introduction: Ecological Importance of Insect Feeding
Insects have mouthparts that may vary greatly across insect species, as they are adapted to particular modes of feeding. The earliest insects had chewing mouthparts. Most specialisation of mouthparts are for piercing and sucking, and this mode of feeding has evolved a number of times idependently. For example, … Se mer Like most external features of arthropods, the mouthparts of Hexapoda are highly derived. Insect mouthparts show a multitude of different functional mechanisms across the wide diversity of insect species. It is … Se mer This section deals only with insects that feed by sucking fluids, as a rule without piercing their food first, and without sponging or licking. … Se mer Labellum The housefly is a typical sponging insect.
