The leek moth or onion leaf miner (Acrolepiopsis assectella) is a species of moth of family Acrolepiidae (formerly Glyphipterigidae) and the genus Acrolepiopsis. The species is native to Europe and Siberia, but is also found in North America, where it is an invasive species. While it was initially recorded in Hawaii, this was actually a misidentification of Acrolepiopsis sapporensis.
The leek moth is similar in appearance to other members of the genus Acrolepiopsis, with mottled brown and white wings. Its wing span is approximately 12 mm across. It is a pest of leek crops, as the larvae feed on several species of Allium by mining into the leaves or bulbs. The shape of the leaf mine is variable, ranging from a corridor to a blotch, and can be with or without frass. This leaf mining can occur in the tubular leaves or in the stem. In the case of onions and shallots, the larvae mine into the bulb. In North America, where the moth is an invasive species and has few known natural predators, the species threatens the production and biodiversity of Allium, and it has the potential to destroy entire crops. The parasitoid Diadromus pulchellus is used to control the spread of and damage caused by the leek moth in Europe and North America. Wikipedia →

Rare
Under 5% of wildlife watchers report a Leek Moth sighting in Montreal on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 634th most-seen of the 926 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Leek Moth in Montreal on a given day, so our monthly data shows no clear season.
3rd of 3
Of the 3 cities where we can rate Leek Moth sightings, Montreal ranks 3rd at under 5%. The best odds are in Liverpool (United Kingdom, about 10%) and Helsinki (Finland, under 5%).
Same order: Lepidoptera
The closest relatives of the Leek Moth that you can see in Montreal (order Lepidoptera, Butterflies and Moths) are Common Blue (about 40%), Monarch (about 30%) and Black Swallowtail (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Leek Moth is recorded against all the insects logged in Montreal (8 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.
