Under 5% of wildlife watchers report a Sacken's Antlion sighting in Mesa on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 205th most-seen of the 232 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.
August
In that month about 10% of wildlife watchers report a Sacken's Antlion in Mesa on a given day, against under 5% in September to July, the lowest months. That is one of Mesa's wettest months, with about 35 mm of rain against almost none in June.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Sacken's Antlion sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Mesa, in our data
Mesa is the only city on Wallace's Line with enough records to rate Sacken's Antlion sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Sacken's Antlion is recorded against all the insects logged in Mesa (5 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.
