Trithemis annulata, commonly known as the violet dropwing, violet-marked darter, purple-blushed darter, or plum-coloured dropwing, is a species of dragonfly in the family Libellulidae. It is found in most of Africa, the Middle East, and southern Europe. These dragonflies are called dropwings because of their habit of immediately lowering their wings after landing on a perch. Males of this species are violet-red with red veins in the wings, while females are yellow and brown. Both sexes have red eyes. Wikipedia →

Rare
Under 5% of wildlife watchers report a Violet Dropwing sighting in Lyon on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 361st most-seen of the 411 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July and September–October
In those months about 10% of wildlife watchers report a Violet Dropwing in Lyon on a given day, against under 5% in August and November–June, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Violet Dropwing sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
22nd of 23
Of the 23 cities where we can rate Violet Dropwing sightings, Lyon ranks 22nd at under 5%. The best odds are in Dammam (Saudi Arabia, about 50%), Antalya (Turkey, about 40%) and Ouagadougou (Burkina Faso, about 40%).
Same family: Libellulidae
The closest relatives of the Violet Dropwing that you can see in Lyon (family Libellulidae, Skimmers) are Black-Tailed Skimmer (about 10%), Common Darter (about 10%) and Broad Scarlet (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Violet Dropwing is recorded against all the insects logged in Lyon (5 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.
