Nyctoporis carinata
In 3 days ~10% in a week ~20%
Nyctoporis carinata, also known as the armored night-walker and the flightless darkling beetle, is a species of beetle native to California along the coast and the Coast Ranges. Adult Nyctoporis carinata reach 12–16 millimetres (0.47–0.63 in) in length. They are black and covered in indentations, bumps, and ridges. Golden hairs are attached to their feet, or tarsi. Because their wing covers are fused, they are flightless. They are found in leaf litter and rocky debris.
Preliminary genetic analysis suggests that Nyctoporis carinata and Nyctoporis vandykei may in fact be synonymous species. Wikipedia →

Rare
Under 5% of wildlife watchers report an Armored Night-Walker sighting in Los Angeles on a given day, based on 28 verified sightings from GBIF citizen-science data. It is the 350th most-seen of the 851 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an Armored Night-Walker in Los Angeles on a given day, so our monthly data shows no clear season.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Armored Night-Walker sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Los Angeles, in our data
Los Angeles is the only city on Wallace's Line with enough records to rate Armored Night-Walker sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Armored Night-Walker is recorded against all the insects logged in Los Angeles (28 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.
