The Twin-spotted Spiketail is a large dark dragonfly with green eyes that come together in a single point and two yellow thoracic side stripes. It is more common than the Arrowhead Spiketail and can be identified by its abdominal spots which come in pairs
Most common spiketail species throughout most of its range. Males typically patrol streams flying low over the water looking for females. Most hunting takes place in forest clearings where it is often found in shadows. Will also fly on cloudy days. They usually begin emerging early in the summer.
Wooded, clear, fast running streams. Woodland clearings.
Mating typically takes place in the tree tops. Females oviposit alone by hovering low over the water and then stabbing there ovipositor into the substrate at the bottom of a stream. They do this repeatedly in quick succession then may move to a new location and repeat the process.
