Archips oporana
In 3 days ~10%
Archips oporana, also known as the pine tortrix or spruce tortrix, is a moth of the family Tortricidae, found in Asia and Europe. It was first described by Carl Linnaeus in 1758. The wingspan is 19–28 millimetres (0.75–1.10 in). In western Europe the moth flies from late May to July, and there is a partial second generation in August and September.
The larvae initially feed in September tying two sets of needles and attach it to the branch of the host plant. They overwinter in a silken tube among the needles. The following year, the larva eat new shoots and may bore into the stem, which can cause them to shrivel and break off. On juniper the larva spins a thick white web amongst the leaves. Pupation is in the larval habitation in June and July. Larva can be found on silver fir (Abies alba), European larch (Larix decidua), common juniper (Juniperus communis), spruce (Picea species), Scots pine (Pinus sylvestris) and cedars (Thuja species).
The moth is found in most of Europe and in Asia it is found in China (Heilongjiang, Liaoning), Korea, Japan and Russia (Primorye). Waarneming.nl (in Dutch). Lepidoptera of... Wikipedia →

Rare
Under 5% of wildlife watchers report a Pine Tortrix sighting in Moscow on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 774th most-seen of the 1111 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 Pine Tortrix in Moscow on a given day, so our monthly data shows no clear season.
Yes
Of the 2 cities where we can rate Pine Tortrix sightings, Moscow has the highest daily chance: under 5%. Next come Toronto (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Pine Tortrix is recorded against all the insects logged in Moscow (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.
