Conservation

Lace bugs are not generally of conservation concern. However, they can have significant impacts on plant health, particularly in agriculture and horticulture settings.

Significance to Humans

  • Agriculture: Some species are considered pests on ornamental plants and can cause significant aesthetic and health damage.
  • Indicator Species: They may indicate the health of the plant ecosystems they inhabit.

Fun Facts

  • Quick Breeders: Lace bugs can produce several generations in a single growing season.
  • Ancient Lineage: Fossils of lace bugs date back to the Jurassic period.
  • Diverse Habitats: Apart from plants, some lace bugs have been found on mosses and lichens.
  • Protective Parents: Some lace bug species exhibit maternal care, with females guarding their eggs and nymphs.
