Locusts

 

Locusts, grashoppers and crickets are a striking and unmistakable animal group in meadows on warm summer days. Particularly interesting for actions are their "singing", their preference to jump and their frequency in the grassland. Their terrible final German name “Schrecke” (engl. “Horror”) has nothing to do with any kind of horror. Furthermore "schricken" is the Old High German word for “jump”. Actually, their name should therefore properly be “Heuspringer” = “hay jumper”. Locusts can be collected and kept easily. Observing them you can watch the incomplete metamorphosis of an insect well and make the acoustic communication understandable.

Main aims of the actions

  • discover the diversity of native grasshoppers
  • develop sensitivity to acoustic signals in nature and recognize their role
  • identify the importance of locusts in the ecosystem
  • arouse interest for locusts as a group of insects with incomplete metamorphosis
  • recognize grasshoppers as part of the biocoenosis “meadow”
