| Scientific Name: | Nannophlebia risi (Tillyard, 1913) |
| Distribution: | Common along the eastern coast of Australia north from Sydney.
There's an apparently separated colony around Wodonga–Wangaratta. |
| Description: | Small black and yellow dragonflies with the end of the abdomen (tail) swollen noticeably. |
| Similar Species: | Similar to the several other Nannophlebia species.
Can be separated somewhat by geography, the patterning on the first few abdominal segments
and that N. risi has a black Vertex (segment on top of the "nose" between the eyes) with yellow on top.
Also somewhat similar to the many Gomphids but can be separated from them by shape and patterning. |
| Habitat: | Mostly inhabits gravely rivers. |
| Behaviour: | Occasionally flies low over water but regularly perches, usually horizontally on small branches. |
| Observations: |
I have observed good numbers of this species along the Ovens River at Wangaratta during January
as well as occasionally further north. |

Although not a rare species there seems to be little in the way of information and additional photos on the web..
