It is widespread in tropical and subtropical regions, while it is a rare migrant in some other parts of its range, such as the UK and the Netherlands.

Rare
Under 5% of wildlife watchers report a Belted Grass-Veneer sighting in Los Angeles on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 407th most-seen of the 851 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 a Belted Grass-Veneer in Los Angeles 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 Belted Grass-Veneer sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.

GBIF citizen-science records
It is estimated from how often the Belted Grass-Veneer is recorded against all the insects logged in Los Angeles (21 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.
