Invertebrates


Benthic invertebrates, more commonly known as bugs, are the insects, worms, mollusks and crustaceans that live at the bottom of a stream. The presence of these species is a good indicator of ecological health. The makeup of their communities can relay information about the types of stresses or pollution that a stream could be facing.

SNC is a partner of the Ontario Benthos Biomonitoring Network, which provides the provincial standard protocol for sampling, processing, and analyzing bugs sampled in local rivers.
