In 3 days ~10% in a week ~20%
Lepidochrysops trimeni, the Trimen's blue, is a butterfly of the family Lycaenidae. It is found in South Africa, where it is known from the Western Cape. The wingspan is 37–40 mm for males and 35–42 mm for females. Adults are on wing from September to January or February, with a peak depending on rainfall but usually from October to November. There is one extended generation per year.
The larvae feed on Selago species (including Selago serrata) and Aspalathus sarcantha. Third and later instar larvae feed on the brood of Camponotus maculatus ants. Wikipedia →

Rare
Under 5% of wildlife watchers report a Trimen's Blue sighting in Table Mountain National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 180th most-seen of the 344 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
November to January
In those months about 10% of wildlife watchers report a Trimen's Blue in Table Mountain National Park on a given day, against under 5% in February to October, the lowest months. Those are among Table Mountain National Park's driest months, with about 25 mm of rain a month against 110 mm in June.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Trimen's Blue sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Table Mountain National Park, in our data
Table Mountain National Park is the only park on Wallace's Line with enough records to rate Trimen's Blue sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Trimen's Blue is recorded against all the insects logged in Table Mountain National Park (12 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.
