Acleris variegana, the garden rose tortricid moth or fruit tortricid, is a moth of the family Tortricidae. It has a Palearctic distribution. The moth flies from July to September mainly at night and is attracted to bright lights. The larvae feed on various trees and shrubs including rose and apple.
The fore wing is parallel-sided with an oblique external margin. The basal half is white or yellowish-white and there is a grayish-brown triangular spot close to the wing root. The distal part of the wing is reddish- or violet-brown, edged by a narrow grayish-yellow strip. The hind wing is brownish-gray. The wingspan is 14–20 millimetres (0.55–0.79 in). Julius von Kennel provides a full description.
The eggs are oval, light yellow for the summer generation and milky-white or orange for over-wintering eggs. The larva is yellowish with a shiny brown head. The pupa is 8–9 mm (0.31–0.35 in) long. Hatching caterpillars in spring eat fruit buds. Later they tie leaves into bundles with the help of webbing that they spin. They can skeletonize young leaves and also do damage to buds, flowers, ovaries and unripe fruits. In spring, eggs are laid in large batches. Moths... Wikipedia →

Rare
Under 5% of wildlife watchers report a Garden Rose Tortrix sighting in Seattle on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 212th most-seen of the 428 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.
September
In that month about 10% of wildlife watchers report a Garden Rose Tortrix in Seattle on a given day, against under 5% in October to August, the lowest months. That is one of Seattle's driest months, with about 60 mm of rain against 190 mm in November.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Garden Rose Tortrix sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
6th of 7
Of the 7 cities where we can rate Garden Rose Tortrix sightings, Seattle ranks 6th at under 5%. The best odds are in London (United Kingdom, about 10%), Manchester (United Kingdom, about 10%) and Birmingham (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Garden Rose Tortrix is recorded against all the insects logged in Seattle (17 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.
