This slender darner is darker than many of the darners seen in NL. There is more brown than blue.
The frontal stripes are lender, straight and greenish.
Similar darners are the Shadow Darner and Sedge Darner. I found it very hard to differentiate them. Pouring over images and readings, I concluded this dragonfly seen in late August in Goulds to be a Black-tipped Darner. With the help of a reader (see comment below) I learned this is a Shadow Darner. Thank you.
