Question: How did the Permian extinction affect insects?  Edit

Answer: Permian extinction or Permian mass extinction or Permian Triassic extinction also referred to as The Great Dying took place about 252.28 million years ago. The extinction event was the most severe extinction event took place on the Earth.

Permian era had a wide diversity of insects including some large insects ever existed on the Earth and other invertebrate species as well. The end of Permian era was the only mass extinction of insects when 8 to 9 insect orders had become diminished, while about 10 more massively reduced in diversity. While insects belong to Palaeodictyopteroids started declining during the mid of Permian, the extinction process was somehow related to some changes in flora. However, the most declining took place during late Permian, though it was not the direct result of weather related floral transition.  Edit
