Macroinvertebrate identification sheet

Use this sheet 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-use when out in the field for macroinvertebrate identification. Before you head out into the stream, print off a few double-sided copies of this sheet for you and your students, or fellow citizen scientists, to use.

This sheet is a great introduction to macroinvertebrates for any student. It makes each benthic macroinvertebrate (BMI) really accessible, and it allows for students to easily compare the BMIs by seeing them side-by-side on a single sheet. Also, going out into the field is a lot easier with one sheet instead of many species cards. This sheet makes BMI identification a no-hassle event. Use this sheet to complement the Mission: Water Quality Bioassessment.
