49.065 BF1039  –  Tortricidae –  Tortricinae – Acleris comariana – Strawberry Tortrix – (Lienig & Zeller, 1846) Adult Micro:  CAT 4 – Gen. Det. Required – Gen-Det-Reqd       PDF Icon – click for General Verification Guidelines  |   PDF Icon – click for Specific Verification Guidelines
Blue –  Generally Common / Widespread   
Taxonomy:   Micro   >>  Tortricidae  >> Tortricinae
ID Difficulty:  amber  – care required in the identification process, as confusion with similar species is likely – quality photographs required.
Confusion Species:  Acleris laterana (Dark-marked Tortrix)
ID pointers: A variable species that has several known forms – Feeds on wild and cultivated Strawberries and can be a pest in Strawberry fields. Has two large brown, orange-brown or dark brown costal triangular wedges on a bright orange-brown or creamy fawn brown forewing. Sometimes the triangular wedges meet at the dorsum.
Distribution:  Likely to be locally common – Most records are recorded as A.laterana/comariana aggregate due to the second brood over-lapping with A.laterana. DaNES list 22 records between 2004 – 2013. Over 200 accounts on iRecord are all recorded as aggregate.
Flight Period: June /  July /  September /  October /  November /  –  Two broods – the first in June & July is before A.laterana but the second brood that flies in late August through to November overlaps and so would need to be recorded as aggregate or Gen Det. Moth Activity: Cathemeral   – and is attracted to light Photographed: No –  Photographed By: Not Recorded
*** Last updated on 7 May 2025 by RP ***
Wingspan: 13-18mm
 Food Plant: Strawberries, Raspberries, Marsh Cinquefoil and Water Avens.

Bedrock Geology ** indirectly affects moth distribution by influencing the type of habitat and food plants available in an area. In turn, this may affect the types of moths that can thrive, or where they can most likely be found.

Land-cover * shows the variety of land-cover within the VC57 area, based on the CORINE (Coordination of Information on the Environment) forty-four thematic classes of land-cover. This will show, to a greater or lesser degree, the number and variety of moths found in different land-cover types. The UK continues to operate within the Copernicus programme, with the UK Centre for Ecology & Hydrology (UKCEH) providing Corine Land Cover (CLC) datasets for the UK and its territories.

CUSUM Analysis: Acleris comariana
About this chart: CUSUM (Cumulative Sum) charts track long-term trends in moth populations [ filtered by 'Adult' and 'Mine' life stages ] by showing whether each year’s counts are above or below the historical average. Even small shifts build up over time, making trends of growth, stability, or decline easier to see. CUSUM highlights trend-consistency — asking: “Across the years, have moth counts mostly stayed above or below average?”
The data sample has 14 gap year/s here (zero records) between 2000 and 2025. The moth may have been present in those gap years, but no data was available. Too many year-gaps may exaggerate or skew the chart.

Counts for the current year (2025) are pro-rated based on data available up to month 7 (July) to provide a full-year equivalent.

ⓘ Purple line rises = years better than average; falls = years worse than average.
Peak (best year) Trough (worst year) Growth periods Decline periods
Population peaked around 2004, reaching above average levels. The lowest population point occurred near 2020, showing a significant decline.

What the Y-axis "Cumulative Deviation" means: Cumulative Deviation shows the running total of how each year’s moth population count differs from the long-term average. i
