Arrowhead Spiketail, named for the distinctive arrowhead-shaped markings on the abdomen. 

This is a female Arrowhead Spiketail. She was flying in the same clearing as the male above. I have also seen this species at Germantown MetroPark. 

Brown Spiketail dragonfly, perched at Cedar Bog. This species perches often and is fairly easy to approach. Notice that it has pairs of yellow, triangular-shaped markings rather than arrowheads. 

A newly-emerged Brown Spiketail with its exuvia. Found along the boardwalk at Cedar Bog, May 28, 2016.

Another Brown Spiketail at Cedar Bog. There is a very similar species called the Delta-spotted Spiketail. However, Delta-spotted Spiketails have not been documented in western Ohio. From what I have read, all of the individuals examined at Cedar Bog have proven to be Brown Spiketails. 

Brown Spiketails fly in late May and early June. The last week of May is usually an ideal time to find them at Cedar Bog. 

This Arrowhead Spiketail was photographed June 2, 2020, at Caesar Creek. This species usually flies in late May and June. The preferred habitat is very small, shallow, fishless streams and trickles, in woods with sunny clearings. 

Brown Spiketails usually live near fens. The individual at left was photographed near Travertine Fen. This location is not accessible without a permit, but there is a public bike path that runs along one edge of Travertine Fen. I found this Brown Spiketail in the ditch right beside the bike path.
