Merrimack, Hillsborough County, New Hampshire, USA
March 27, 2018
Size: ~5/8 - 3/4 in
Not sure if it is the same kind, but a couple of weeks ago I saw a large number of stoneflies crawling on the snow at the local park, ranging tremendously in size from about 1/8 inch to 3/4 inch. This one was on the house's siding at home.
