Orthetrum julia, the Julia skimmer, is a species of dragonfly in the family Libellulidae. It is found in Angola, Benin, Burkina Faso, Cameroon, Central African Republic, the Republic of the Congo, the Democratic Republic of the Congo, Ivory Coast, Equatorial Guinea, Ethiopia, Gabon, Gambia, Ghana, Guinea, Kenya, Liberia, Malawi, Mozambique, Namibia, Nigeria, São Tomé and Príncipe, Senegal, Sierra Leone, South Africa, Sudan, Tanzania, Togo, Uganda, Zambia, Zimbabwe, possibly Burundi, and possibly Madagascar.
Its natural habitats are subtropical or tropical moist lowland forests, rivers, and freshwater springs. Orthetrum stemmale appears similar to O. julia falsum in south-eastern Africa. The important differences are in wing details shown in the figure (left). O. julia falsum (top) has dark subcostal Ax and has one row of cells in the radial planate (generally less than 10 cells doubled - summed over the radial planates of the four wings). This example shows a single doubled cell on each wing. O. stemmale (bottom) has pale subcostal Ax and usually at least ten cells doubled in total over the four wings - this example... Wikipedia →

Possible
About 20% of wildlife watchers report a Julia Skimmer sighting in uMkhuze Game Reserve on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 41st most-seen of the 59 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
February, April and October–November
In those months about 30% of wildlife watchers report a Julia Skimmer in uMkhuze Game Reserve on a given day, against under 5% in March, May–September and December–January, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Julia Skimmer sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
6th of 8
Of the 8 parks where we can rate Julia Skimmer sightings, uMkhuze Game Reserve ranks 6th at about 20%. The best odds are in Waterberg Plateau Park (Namibia, about 40%), Garden Route National Park (South Africa, about 30%) and Table Mountain National Park (South Africa, about 20%). All parks ranked.
Same genus: Orthetrum

GBIF citizen-science records
It is estimated from how often the Julia Skimmer is recorded against all the insects logged in uMkhuze Game Reserve (7 verified sightings from 2019 to 2026), 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.
