Uncommon Insect observations in Vermont

Dolichopus brevimanus @iNaturalist user bugeyedbernie


Uncommon insect species

by Bernie Paquette (bugeyedbernie on iNaturalist)


Uncommon: out of the ordinary, unusual, or remarkably great. In 2012 the Polystoechotes punctata or giant lacewing was the first recorded in eastern North America in over 50 years — and the first record of the species ever in Arkansas (at a Walmart). Vermont also has had a share of uncommon discoveries. Thankfully there is no need to travel to Arkansas or Walmart to discover and observe an uncommon insect taxa. 


One can appreciate the perseverance of Bryan Pfeiffer, who after searching for two decades discovered (first for Vermont) a rare and elusive butterfly, the Bog elfin in 2023. 


Most of us will never see a Bog elfin, and many will never see a bog. However, uncommon finds can be had closer to home, even in our own yards. 


As my list below demonstrates, the next uncommon insect discovery may be awaiting in your town or your backyard. 


"You need to go nowhere to see wonders." 

Jack Gedney, The Private Lives of Public Birds.


Below are a few uncommon* discoveries, most from our Jericho, VT backyard, and a few from nearby towns, that I posted on iNaturalist in 2024. *Here I am defining uncommon as 5 or fewer posts on iNaturalist in Vermont at the time of my observation. There may be more on GBIF.

Insect names are hyperlinked to the iNaturalist post. I appreciate any additional help with IDs on those not yet at Research Grade.

*R.G. indicates Research Grade on iNaturalist.

"The greatest human discoveries in the future will be the discovery of human intimacy with all those other modes of being that live with us on this planet, inspire our art and literature, reveal that numinous world whence all things come into being, and with which we exchange the very substance of life." 
- The Great Work - our way into the future, Thomas Berry
