With luck
About 10% of wildlife watchers report a Dichillus subcostatus sighting in Sierra Nevada National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 390th most-seen of the 479 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
March and November
In those months about 30% of wildlife watchers report a Dichillus subcostatus in Sierra Nevada National Park on a given day, against under 5% in April, June–October and December–February, the lowest months. Those are among Sierra Nevada National Park's wettest months, with about 90 mm of rain a month against 30 mm in July.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Dichillus subcostatus 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 Dichillus subcostatus sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Tenebrionidae
The closest relatives of the Dichillus subcostatus that you can see in Sierra Nevada National Park (family Tenebrionidae, Darkling Beetles) are Heliotaurus ruficollis (about 20%), Proctenius granatensis (about 20%) and Pimelia monticola (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dichillus subcostatus is recorded against all the insects logged in Sierra Nevada National Park (8 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.
