Freshwater macroinvertebrates

Macroinvertebrate Identification Sheet:

    Use the sheet below for easy identification of macroinvertebrates out in the field. The sheet is designed to work either as a companion sheet to work with species cards or as a stand-alone resource. This sheet makes macroinvertebrate identification easy: organisms are grouped by pollution tolerance class and relative sizes are given for the organisms along with hand-drawn sketches and short identification pointers. It is a must-have when out in the field for macroinvertebrate identification. Before you head out into the stream, print off and laminate a few double-sided copies of this sheet for you and your students, or fellow citizen scientists, to use.
