Insect Hatch Field Guide

Our chapter is very fortunate to have Mike Cole as one of its active members. Mike is an expert in the field of acquatic insects and their fascinating life cycles. With funding from Trout Unlimited national and the River’s Calendar Project, Mike carefully researched and wrote “A Field Guide To Common Aquatic Insect Hatches in Massachusetts”, a 45 page compendium of information complete with stunning photos of the nymphs, duns and spinners of the major hatches on Massachusetts waters.
