Identification
Amber patch at the base of each hindwing; black stripe along the dorsal edge of the abdomen.
Range
Native from southern Japan and China to northern Australia. Introduced accidentally to south Florida and to Oahu, Hawai'i.
Habitat
In the US, typically uses low-quality wetlands, either artificially constructed or highly degraded, where low dissolved oxygen, introduced fish, or other alterations make the habitat unsuitable for sensitive native species.
Remarks
One report from Chattanooga, Tennessee was not repeated in successive years and probably resulted from larvae in the roots of water plants being shipped north from Florida for the nursery trade.
