Rare
Under 5% of wildlife watchers report a Protean Shieldback sighting in Washington on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 1121st most-seen of the 1807 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 a Protean Shieldback in Washington on a given day, so our monthly data shows no clear season.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Protean Shieldback sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Washington, in our data
Washington is the only city on Wallace's Line with enough records to rate Protean Shieldback sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Tettigoniidae
The closest relatives of the Protean Shieldback that you can see in Washington (family Tettigoniidae, Katydids) are Short-Winged Meadow Katydid (about 10%) and Handsome Meadow Katydid (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Protean Shieldback is recorded against all the insects logged in Washington (15 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.
