Did you know?
Spiketail dragonflies are so named because the long ovipositor of the female extends beyond the tip of the abdomen. The females lay their eggs by hovering over shallow water and driving the long ovipositor vertically into the shoreline mud or stream bottom in a fashion reminiscent of a sewing machine.
|State Ranking Justification||
This species has been recorded from approximately 16 locations in 11 separate counties across a broad extent of the southern tier, Finger Lakes, and Hudson Valley, and a number of these locations have been found in the past 5-10 years. The habitat is not uncommon within the broad range occupied by the species and many additional populations will undoubtedly be discovered as a result of more extensive survey efforts. However, there are a number of potentially significant threats to the habitat required by these dragonflies and populations at individual sites are not expected to be large.
There is no information on population trends for this species although it seems likely that suitable sites are being lost due to development and hydrological changes in proximity to seepage areas and small forest streams.
