Rare
Under 5% of wildlife watchers report a Vetch Looper Moth sighting in Houston on a given day, based on 35 verified sightings from GBIF citizen-science data. It is the 328th most-seen of the 1057 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.
May
In that month about 10% of wildlife watchers report a Vetch Looper Moth in Houston on a given day, against under 5% in June to April, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Vetch Looper Moth sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 cities where we can rate Vetch Looper Moth sightings, Houston ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Miami (United States, under 5%).
Same family: Erebidae
The closest relatives of the Vetch Looper Moth that you can see in Houston (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Salt Marsh Moth (about 20%), Fall Webworm Moth (about 20%) and Green Cloverworm Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Vetch Looper Moth is recorded against all the insects logged in Houston (35 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.
