In 3 days ~20% in a week ~50%
The E. bipunctella invalidly described in 1936 by H. Rebel in L. Osthelder is actually E. distigmatella. Ethmia bipunctella is a diurnal moth from the family Depressariidae. It can be found in Central and Southern Europe, North Africa, Asia and the northeastern part of North America. E. iranella was formerly included here as a subspecies.
The wingspan of the moth ranges from 19–28 millimetres (0.75–1.10 in). The flight time ranges from May to September. The moth is bivoltine, having two generations per year. The most important host plant is the viper's bugloss, but also Anchusa officinalis and plants from the genus Symphytum. Pupae are attached to dead wood. Wikipedia →

With luck
About 10% of wildlife watchers report a Viper's Bugloss Moth sighting in Doñana National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 58th most-seen of the 87 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
June and September
In those months about 20% of wildlife watchers report a Viper's Bugloss Moth in Doñana National Park on a given day, against under 5% in April–May, July–August and November–February, the lowest months. Those are among Doñana National Park's driest months, with about 15 mm of rain a month against 90 mm in October.

Across all the parks we cover, that three-hour window holds the most Viper's Bugloss Moth sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 6 parks where we can rate Viper's Bugloss Moth sightings, Doñana National Park ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Monfragüe National Park (Spain, about 10%) and Sierra Nevada National Park (Spain, about 10%).

GBIF citizen-science records
It is estimated from how often the Viper's Bugloss Moth is recorded against all the insects logged in Doñana National Park (6 verified sightings from 2019 to 2026), 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.
