Rare
Under 5% of wildlife watchers report a Greater Arid-Land Katydid sighting in Monterrey on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 327th most-seen of the 413 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.
September
In that month about 10% of wildlife watchers report a Greater Arid-Land Katydid in Monterrey on a given day, against under 5% in October to August, the lowest months. That is one of Monterrey's wettest months, with about 200 mm of rain against 20 mm in February.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Greater Arid-Land Katydid sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Monterrey, in our data
Monterrey is the only city on Wallace's Line with enough records to rate Greater Arid-Land Katydid sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Greater Arid-Land Katydid is recorded against all the insects logged in Monterrey (6 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.
