Rare
Under 5% of wildlife watchers report a Locust Twig Borer Moth sighting in Boston on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 967th most-seen of the 1200 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 Locust Twig Borer Moth in Boston on a given day, so our monthly data shows no clear season.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Locust Twig Borer Moth sightings with a recorded time, and nearly all 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 Locust Twig Borer Moth sightings, Boston ranks 4th at under 5%, level with the leaders once rounded. The best odds are in Washington (United States, under 5%), New York City (United States, under 5%) and Toronto (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Locust Twig Borer Moth is recorded against all the insects logged in Boston (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.
