Austrophlebia costalis is an enormous dark dragonfly with strong yellow markings on its body and a brown band along the leading edge of its wings.[4]
It inhabits streams and may be found on logs in shady areas.[5]
This species is believed to be one of the fastest flying
odonates, with an old reference claiming to have clocked one at nearly 60 miles per hour (97 km/h) but no modern confirmation.[6]
