Homoptera – plant-sucking insects

Homoptera means “same wings.” Homoptera must suck large amounts of plant fluids, & much can’t be digested. Extra fluids are excreted as “honeydew”- collected by ants as food.


  • Front wings (when present) are uniform in structure (either membranous or slightly thickened. Most species have 2 pairs of wings and are held “tent like” over body.
  • Includes cicadas, treehoppers, spittlebugs, aphids, leaf hoppers, & scale insects.
  • Plant feeders. Have long beaks for mouth parts used to pierce plant tissue.
  • Found worldwide with many species yet to be described.
  • Species may be hard or soft bodied, smooth or hair-covered
