Definitely smaller than several A. pygmaea seen nearby. Also, compare with @e-aus-kanada 's recent observation of the same species: https://www.inaturalist.org/observations/5408003

This Small Winter Stonefly (Family Capniidae, Genus Allocapnia) was seen just a few meters away from some open water along Dickson Brook. My trusty Swiss Army Knife ruler tells me it was between 7.5 and 8 mm long, minus the cerci at the end of the tail. I think that means this is either Allocapnia pygmaea or A. recta. A. recta is supposed to be the first to emerge in the spring, and this was certainly early. I saw at least thee individuals. Allocapnia pygmaea is known for the park. Allocapnia recta is not known for New Brunswick yet, but it is present in neighbouring Nova Scotia, Maine and Quebec.

I finally saw some individuals that show the structures near the end of the tail that can be ID'd properly by image alone. Compare with: http://bugguide.net/node/view/258035/bgimage This is the same species I found here at the end of February last year, but ID'd by length rather than structure. It is nice to be able to better confirm their ID. http://inaturalist.ca/observations/2690859

At least a dozen seen. I think this is my best shot of the species to date, so I am quite happy with it. I will also post it on Bug Guide.
