Description
Despite their unassuming appearance, these insects are top-tier indicators of water quality. The presence of Perlodidae in a stream or river often signifies pristine water conditions, as they are intolerant to pollution. Contrary to certain myths, Perlodidae are neither harmful to humans nor do they possess any venomous traits; instead, their larvae are essential for breaking down organic matter, thus supporting the riverine food web. Their existence challenges the often overlooked importance of invertebrates in maintaining ecological balance.
