Adults are on wing from July to October. The larvae feed on Rosa acicularis, Rosa × bifera, Rosa canina, Rosa centifolia, Rosa glauca, Rosa 'Hybrida', Rosa jundzillii, Rosa majalis, Rosa multiflora, Rosa pendulina, Rosa phoenicea, Rosa pimpinellifolia, Rosa rubiginosa, Rosa soulieana, Rosa tomentosa, Rosa wichurana, Sanguisorba hybrida, Sanguisorba minor and Sanguisorba officinalis. Larvae have also been reared from Alchemilla species. They mine the leaves of their host plant. Unlike the mines of Stigmella anomalella, this species' meandering mines rarely run along the outer edge of the leaves. The species probably has two generations each year. Wikipedia →

Rare
Under 5% of wildlife watchers report a Narrow-Barred Pigmy sighting in Los Angeles on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 626th 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 Narrow-Barred Pigmy in Los Angeles on a given day, so our monthly data shows no clear season.
Among the best
Of the 2 cities where we can rate Narrow-Barred Pigmy sightings, Los Angeles ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in San Francisco (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Narrow-Barred Pigmy is recorded against all the insects logged in Los Angeles (9 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.
