Lake Clark National Park and Preserve, Alaska – From inside a camping tent, a video shows hundreds of big spiders gathered tightly on the tent’s screen.

The unusual sight reveals the spiders pressed against the mesh, creating a striking and eerie view.

These groups, known as aggregations, are common among daddy longlegs but the reason for this behavior is still uncertain.

Scientists suggest the clusters may help with mating, humidity control, or protection from predators.

This happens more often in autumn when dry weather and shorter days increase the risk of drying out.

By clustering, the spiders maintain a humid environment crucial for survival.

This footage highlights the curious and surprising ways nature adapts.
