Sphex lucae
In 3 days ~10%
Sphex lucae is a species of thread-waisted wasp in the family Sphecidae. Sphex lucae is predominantly found in western North America, but specimens have also been collected in Georgia and Florida.Entomologist Henry T. Fernald described this wasp as: "Body rather slender; the head and thorax black; the abdomen black to red, the two colors variously mingled in different examples, the males being generally much darker than the females; wings varying from yellowish hyaline with a fuliginous tinge to deep fuliginous with a violet reflection; legs dark ferruginous to black." Richard M. Bohart and Arnold S. Menke proposed moving this wasp to the monotypic genus Fernaldina. The main body of research on this wasp prior to 1965 regarded its propensity for communal roosting on plants. Wikipedia →

Rare
Under 5% of wildlife watchers report a Sphex lucae sighting in Los Angeles on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 490th most-seen of the 851 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Sphex lucae in Los Angeles on a given day, so our monthly data shows no clear season.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Sphex lucae sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Sphex lucae sightings, Los Angeles ranks 4th at under 5%, level with the leaders once rounded. The best odds are in San Francisco (United States, under 5%), San Diego (United States, under 5%) and Portland (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Sphex lucae is recorded against all the insects logged in Los Angeles (19 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.
