Where have the insects gone?

The natural, but also the man-made and used biological diversity , the so-called agrobiodiversity, is declining . This development can be seen worldwide – but also in Austria.  

The loss of ecosystems that are biologically worthy of protection due to settlement and road construction and conversion to intensively cultivated grassland and arable land is increasing year by year .  


Soil sealing and intensive agriculture have long threatened insect habitats.  Fields are heavily fertilized and mineral fertilizers and pesticides are often applied.

Wild bees, hoverflies and butterflies play a special role among the insects.  Not only do they pollinate wild and cultivated plants, they are also part of the important diversity of species.


It's shortly before twelve - we have to actively campaign for insect-friendly land management.  The preservation and promotion of native biodiversity are central future tasks for all of us .

Central factors for the decline in insect populations are:  

  • the unrestrained surface sealing through settlement and road construction  

  • the changes in the landscape structure due to the increase in intensively used agricultural monocultures

  • the use of mineral fertilizers, liquid manure and pesticides

  • the compaction of the soil by working the land with heavy agricultural machinery

  • the far too frequent mowing of forage areas and grassland (up to 6x a year)

  • the rapid decline of species-rich ecosystems such as flower meadows, fringes, hedges, meadow orchards and other field shrubs and the associated loss of habitats and food sources.

The most important measures to preserve pollinator insects are:

  • the creation of flower areas and flower strips as well as protection strips

  • the expansion of extensive grassland management

  • the restriction to ONE mowing per year after flowering and seeding of the meadow flowers

  • the care and maintenance of hedges, bends, rows of trees, copses and meadow orchards

  • and the conversion and retention of organic farming.

Our native insect species


There are around 30,000 native species of insects. Do you have to know them all? No, you can't know them all! However, some insects are so common that it is worth getting to know them.  introduces moths, bees, beetles, flies, bugs and dragonflies



Heinrich Böll Foundation - Podcast - Insects

70% of all animal species worldwide are insects
and yet they are currently under threat.

Why are insects dying out en masse and what does that have to do with our agriculture?

Where it used to buzz, crawl and flutter, there are far fewer insects to be found today.
But you can do something to stop insects from dying: in agriculture and in the forest, but also in your own garden.
