Massachusetts Odonate County List

Spiketails (Cordulegastridae), Cruisers (Macromiidae) & Emeralds (Corduliidae)



This page was updated on 16 January 2006.

This list was originally compiled by Chris Leahy, revised by Richard Forster, and has been updated by Blair Nikula, Jackie Sones, Jeremiah Trimble and others.

Most records are based upon specimens or, in a few cases, capture and release. Sight records have been accepted only for a few easily identified species.

"H" indicates a species known only historically (pre-1950). Counties are arranged in a generally west to east, then north to south order.
