Oecophora bractella
In 3 days ~10% in a week ~30%
Oecophora bractella is a species of gelechioid moth, native to Europe but introduced to western North America. It belongs to the subfamily Oecophorinae of the concealer moth family (Oecophoridae). As the type species of its genus Oecophora, its affiliations and phylogeny (which are not completely known however) determine the delimitation of that family and subfamily.
In its native Europe, it inhabits woodland. The species is not often found in the outlying regions; in the UK for example it has only been recorded from a few patches of old-growth forest in the English Midlands (e.g. Wyre Forest), southern England, and southern Wales (e.g. in the Wye valley).
The adults' wingspan is 12–16 mm. Conspicuously bicolored black and yellow, they also have some iridescent blue markings on the forewings. The adult moths fly from May to July depending on the location; they are semi-diurnal and can be encountered during the day, but usually are active at dawn. The caterpillars feed on dead and decaying wood, and possibly also on fungi.
This species has suffered from considerable confusion regarding its scientific name. It was first described... Wikipedia →

Rare
Under 5% of wildlife watchers report a Gold-Base Tubic sighting in Vancouver on a given day, based on 48 verified sightings from GBIF citizen-science data. It is the 129th most-seen of the 482 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
May to July
In those months about 10% of wildlife watchers report a Gold-Base Tubic in Vancouver on a given day, against under 5% in August to April, the lowest months. Those are among Vancouver's driest months, with about 45 mm of rain a month against 210 mm in November.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Gold-Base Tubic sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Yes
Of the 2 cities where we can rate Gold-Base Tubic sightings, Vancouver has the highest daily chance: under 5%. Next come Seattle (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Gold-Base Tubic is recorded against all the insects logged in Vancouver (48 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.
