"These things... I remember they're supposed to be social creatures." Qin Ziwen frowned. He recalled the information in the bestiary, which recorded that the Forest Giant Mayfly was an aquatic insect that lived long-term at the bottom of lakes and rivers.
In this form, they typically remain for three to four years.
During this period, they would usually gather at the bottom of wide bodies of water, feeding on small fish, algae, and aquatic plants.
As they approached adulthood, they would typically swim against the current, moving toward the forested regions of the river's upper reaches, devouring every aquatic creature they encountered along the way.
This was partly because food was more plentiful in the forest regions, and partly a form of "regression," similar to the river-to-lake migration of certain salmon.
Every year, when it was time to produce offspring, they would swim upstream from freshwater lakes and rivers, returning to the place that had first nurtured them.
