Diplacodes melanopsis is a species of dragonfly in the family Libellulidae known commonly as the blackfaced percher or black-faced percher. It occurs on the Australian mainland from around Brisbane to the South Australian-Victorian border.
Diplacodes melanopsis is a small dragonfly. Mature males have a black face and front of its body, and a red abdomen with black markings; females are amber and yellow with black markings. The genus name Diplacodes combines Diplax, a genus name derived from the Greek δίς (dis, "twice") and πλάξ (plax, "flat and broad"), with the Greek suffix –ώδης (-ōdēs, "resembling" or "having the nature of"). The name refers to the similarity of the genus to Diplax and Diplacina.
The species name melanopsis is derived from the Greek μελαν- (melan, "black") and ὄψις (opsis, "face" or "appearance"), referring to its brilliant black face. Wikipedia →

With luck
About 10% of wildlife watchers report a Black-Faced Percher sighting in Sydney on a given day, based on 73 verified sightings from GBIF citizen-science data. It is the 142nd most-seen of the 742 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
May and November–March
In those months about 10% of wildlife watchers report a Black-Faced Percher in Sydney on a given day, against under 5% in April and June–October, the lowest months.

GBIF citizen-science records
It is estimated from how often the Black-Faced Percher is recorded against all the insects logged in Sydney (73 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
