How many insect species are there?

Are insect populations declining?
In 2019, Biological Conservation reported that 40% of all insects species are declining globally and that a third of them are endangered.
How does climate change affect insects?
An increase in temperature increases physiological activity and, therefore, metabolic rates. Insects must eat more to survive and it’s expected that insect herbivores will consume more and grow faster. This will lead to increases in the population growth rate of certain insects.
What is the largest biomass on Earth?
The most successful animal species, in terms of biomass, may well be Antarctic krill, Euphausia superba, with a fresh biomass approaching 500 million tonnes. However, as a group, the small aquatic crustaceans called copepods may form the largest animal biomass on earth.

Why are there no bugs in Europe?
To the south, in both Europe and North America, most researchers say the likely primary drivers of most insect population declines so far are habitat loss and degradation, and pesticide use — not climate change. “Climate change is so far very low on the list of causes,” says Ssymank, referring to European insects.

Why are tropical bugs so big?
Abundant food, a year-round growing season and warm weather are all reasons that big insects thrive in the tropics, said Matan Shelomi, a graduate student in entomology at the University of California, Davis. For animals, such as mammals, that rely on internal heat, it pays to be bigger in the colder climes.
What mammal has the most biomass?
Staggeringly, cow biomass exceeds 650 million tonnes (1.3 billion cattle conservatively weighing 500kg each).
