Female Russet-tipped Clubtails have smaller, thinner clubs than the males.

This is a Russet-tipped Clubtail. This species belongs to the family of hanging clubtails, which are generally very difficult to find, because they spend much of their time perched in trees where they are difficult to spot. 

Russet-tipped Clubtails fly later in the year than most clubtail species. I have found several individuals along the Great Miami River in Miamisburg, in August and September. My personal early and late dates are August 1st and September 29th.
