Insect Die-Off: Even Common Species Are Becoming Rare
The number of insects continues to decrease – in some regions, a dramatic decline by up to 75 percent has been recorded in recent decades. “Until now, we assumed that it is primarily the specialists among the insects, i.e., animals that depend on a specific habitat, that are threatened with extinction,” explains Professor Dr. Thomas Schmitt, director of the Senckenberg German Entomological Institute, and he continues, “In our recent study, we were able to show that even so-called “ubiquitous species” will be facing massive threats in the future.”

The insect researchers from Munich and Müncheberg refer to a “temporal shift in the potential causes for the decline of species.” Initially, it is primarily those insects that specialize in a particular ecosystem, e.g., the Mountain Apollo (Parnassius apollo) butterfly, which will be threatened by the loss of high-quality habitats. But over time and with the further deterioration of habitats as well as the collapse of entire habitat networks, the threat to widespread, “undemanding” species such as the Pearly Heath (Coenonympha arcania) also increases.
“In terms of practical nature conservation, these results signify that in the future it will no longer be sufficient to preserve small, isolated reserves – while these benefit specialized species with a simple genetic structure, the bulk of species that depend on an exchange between local populations will lose out in the medium to long term,” predicts Schmitt, and he adds in closing, “This will lead to a further decline of numerous insect species – with dramatic consequences for entire food webs and ecosystems.”

Insect populations including even flies and ants are down 80-95% here in California
everywhere not just near cities and due to loss of habitat. The situation is far more
dire than this puff piece article state. Geoengineering the skies with toxic aluminum,
barium, strontium, and other toxins are much to blame but so is the massive increase
in UV and ionizing radiation from Fukushima as well as the years of damage to the ozone
layer. Also look at the enormous EMF radiation blanketing the earth and you have a cocktail
blend equaling a lifeless planet in the near future. To the delight of many it appears.
Agreed. I don’t see many insects I saw when I was a kid. Most common birds are gone. Use to see them all over by the dozens everywhere. Canary in the mine??
It is predicted that all the water will be polluted in the last day’s along with many other things, it’s all in the ble.
