In the 1980s, a mysterious swarm of stoneflies suddenly appeared on an island in Lake Erie, USA. The island had been previously devoid of stoneflies for over a decade, and scientists were baffled as to how they had managed to recolonise it.

After much investigation, scientists believe that the stoneflies may have been carried to the island by a powerful storm. The storm would have lifted the stoneflies from their original habitat on the mainland and deposited them on the island.

This theory is supported by the fact that the stoneflies that appeared on the island were all of the same species as those found on the mainland. Additionally, the stoneflies appeared on the island shortly after the storm, suggesting that they had been transported by it.

The recolonisation of the island by stoneflies is a fascinating example of how nature can adapt and thrive even in the face of adversity. It also highlights the importance of understanding the natural world and the forces that shape it.
