In 3 days ~10%
Benacus griseus is a species of giant water bug in the family Belostomatidae. It is the only species in the genus Benacus, which was formerly considered a subgenus of Lethocerus. Benacus griseus is found throughout eastern North America, from New England, west through southern Ontario and to Nebraska, south to Florida and Texas, along the Gulf of Mexico coast in Mexico, and into Cuba.
Adults reach lengths of 47–64 mm, making them one of the largest aquatic insect species found in eastern North America. It is distinguished from other Lethocerinae species by the lack of a groove on its front femur. It is also characterized by a wide hind tibia and black ventral stripes. Wikipedia →

Rare
Under 5% of wildlife watchers report an Eastern Toe-Biter sighting in Washington on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 1330th most-seen of the 1807 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 an Eastern Toe-Biter in Washington on a given day, so our monthly data shows no clear season.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Eastern Toe-Biter sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 4 cities where we can rate Eastern Toe-Biter sightings, Washington ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Orlando (United States, under 5%), Miami (United States, under 5%) and Houston (United States, under 5%).
Same order: Hemiptera
The closest relatives of the Eastern Toe-Biter that you can see in Washington (order Hemiptera, True Bugs, Hoppers, Aphids, and allies) are Spotted Lanternfly (about 40%), Large Milkweed Bug (about 20%) and Brown Marmorated Stink Bug (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eastern Toe-Biter is recorded against all the insects logged in Washington (8 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.
