Possible
About 20% of wildlife watchers report a Southern Skimmer sighting in Rostov-on-Don on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 2nd most-seen of the 35 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
June to August
In those months about 40% of wildlife watchers report a Southern Skimmer in Rostov-on-Don on a given day, against under 5% in January–May and September–November, the lowest months.

GBIF citizen-science records
It is estimated from how often the Southern Skimmer is recorded against all the insects logged in Rostov-on-Don (27 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.
