With luck
About 10% of wildlife watchers report a Sloe Hairstreak sighting in Prague on a given day, based on 70 verified sightings from GBIF citizen-science data. It is the 141st most-seen of the 724 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June
In that month about 20% of wildlife watchers report a Sloe Hairstreak in Prague on a given day, against under 5% in August to May, the lowest months. That is one of Prague's wettest months, with about 80 mm of rain against 30 mm in February.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Sloe Hairstreak sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Prague, in our data
Prague is the only city on Wallace's Line with enough records to rate Sloe Hairstreak sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Lycaenidae
The closest relatives of the Sloe Hairstreak that you can see in Prague (family Lycaenidae, Gossamer-winged Butterflies) are Common Blue (about 30%), Small Copper (about 10%) and Holly Blue (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sloe Hairstreak is recorded against all the insects logged in Prague (70 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.
