Gnophaela vermiculata, sometimes known as the police-car moth or green lattice, is a moth of the family Erebidae. The species was first described by Augustus Radcliffe Grote in 1864. It is found in the Rocky Mountain region of the United States and in western parts of North America, from British Columbia to California, east to New Mexico and north to Alberta Manitoba.
The wingspan is about 54 millimetres (2.1 in). Adults are on wing in late summer and fly during the day. There is one generation per year. The larva is born with yellower patches but eventually grows into the adult coloring. As larvae, they feed on Mertensia, Lithospermum and Hackelia species. Adults feed on nectar of various herbaceous flowers, including Cirsium and Solidago.
It can be confused with Gnophaela latipennis because of the similarity in their pattern. The latter species has smaller pale areas on its wings and more rounded forewing margins.

With luck
About 10% of wildlife watchers report a Police Car Moth sighting in Calgary on a given day, based on 215 verified sightings from GBIF citizen-science data. It is the 13th most-seen of the 256 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Police Car Moth is recorded against all the insects logged in Calgary (215 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.
