Rolled-winged stoneflies
Scientific name: Leuctridae
Description
Leuctridae inhabit clean, cool streams, embodying the pristine nature of their environments. These insects possess a distinctive life cycle, spending the majority of their lives as nymphs underwater, a fact which underscores the importance of aquatic health for their survival. Contrary to what one might expect, adult Leuctridae do not feed; they live solely to reproduce, showcasing a fascinating example of evolutionary adaptation. This characteristic highlights their ephemeral adult phase, focusing solely on the perpetuation of the species. The presence of Leuctridae in a water body often serves as an indicator of good water quality.
