Plebicula golgus
In 3 days ~40% in a week ~70%
Polyommatus golgus, the Sierra Nevada blue, is a species of butterfly in the family Lycaenidae. It is endemic to Spain with habitat in the Sierra Nevada in Andalusia (Granada and Almería provinces), and is an endangered species.
It is a small butterfly (forewing length is 11 to 16 mm) that has a sexual dimorphism, the upperside of the male is bright blue to light sky blue, that of the female is brown, decorated with a submarginal line of large orange macules. Both sexes have their wings lined with a white fringe. The underside is light ochre to brownish-grey adorned with a submarginal line of white lunula centred by a more or less marked black point and discreetly surrounded by orange. The forewing verso of the male has six to seven postdiscal spots. On the hindwing verso there are from eleven to thirteen spots: two to four basal, one discal and from seven to eight postdiscal. The discal spot is triangular and is almost without black scales in its centre, so that the white area of the spot is quite wide. Submarginal lunules are of pale orange colour, they are variable in number and size and close to them are noticeable black marginal spots. Wikipedia →

Possible
About 20% of wildlife watchers report a Plebicula golgus sighting in Sierra Nevada National Park on a given day, based on 48 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 103rd most-seen of the 479 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.
July
In that month about 40% of wildlife watchers report a Plebicula golgus in Sierra Nevada National Park on a given day, against under 5% in August to May, the lowest months. That is one of Sierra Nevada National Park's driest months, with about 30 mm of rain against 130 mm in March.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Plebicula golgus sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Sierra Nevada National Park, in our data
Sierra Nevada National Park is the only park on Wallace's Line with enough records to rate Plebicula golgus sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Plebicula golgus is recorded against all the insects logged in Sierra Nevada National Park (48 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.
