State listed species

Updated Sep 2019

Every few years, the state of Michigan tasks various committees of experts with reviewing threatened and endangered species, as required by law. The past two cycles, Julie Craves has been a member of the Insect Technical Advisory Committee.

The committee works to form recommendations on elevations, downgrades, additions, and subtractions to the list, which then goes through a review process that includes internal review and public comment before being signed into law.

There were multiple changes made to the Odonata in the recommendations submitted in 2014-2015 that were not acted upon by the state. The Committee is once again revising the list, and additional changes to the status of a number of Odonata are being proposed. While the lists for all taxa had to be completed by September 2019, it’s unknown due to covid-19 delays when they will be finalized.

Meanwhile, here is the current, albeit outdated, list:

Smoky Rubyspot – Hetaerina titia (Drury) state special concern
Gray Petaltail – Tachopteryx thoreyi (Hagen) state threatened
Splendid Clubtail – Gomphurus lineatifrons (Calvert) state special concern
