Green –  Uncommon / Scarce         purple – Leaf-miner
Taxonomy:   Micro   >>  Bedelliidae
Other Name/s: Bindweed Bent-wing
ID Difficulty:  amber  – care required in the identification process, as confusion with similar species is likely – quality photographs required.
ID pointers: The moth is widespread across southern Britain and is susceptible to huge fluctuations in numbers. It has an overall creamy pale brownish forewing that is littered with a darker speckling. It sometimes shows a small dark spot on the dorsum and at the tornus. Shows a heavily tufted head. A very thin looking moth.
Distribution:  This appears to be a new species for the VC57 Derbyshire. A record that is mentioned on UK Moths from 1998 is being looked into but so far there is no confirmed data from any current source.
An adult was recorded from a garden light trap in Chaddesden on 29th July 2025 representing the first confirmed record. Another adult recorded at Shirland on 30th July 2026. Suspect this moth is overlooked as c100 leaf mines discovered on Bindweed at Gleadless Valley on 30th July 2026. On 1st August at least three more leaf mine sites were discovered in the Gleadless Valley. On 5th August leaf mines found at Markham Vale, North Tip
General Comment: None
Flight Period: January /  February /  March /  April /  May /  August /  October /  November /  December –  Two generations – August and Oct-May – The species likes mild winters. Mine Period:  July /  August /  September
Mine Period Additional: None.
Mine ID Difficulty:  Red Mine Leaf – Mine cannot be identified without breeding through and then adult may need to be examined by Gen Det Prep.
Mine Type/s:  Gallery, Blotch
Mine Feeding Method/s: Not Recorded
Mine Comment: The distinctive larvae feeds on Bindweeds during July-August and September. Firstly making a narrow gallery mine that is filled with frass. Then makes large translucent yellowish blotch mines, from here the frass is ejected. The science is interesting as the larvae make silken threads underneath the leaves in which they move around.

(click legend below to show/hide datasets)
This chart summarises all available historical occurrence records collated by ISO week of the year. It reflects recorder effort and sampling distribution as well as true biological activity, and should be interpreted as an indicative pattern of seasonal occurrence rather than a statistically controlled abundance or phenology model.


Changes in First and Last Recorded Activity Dates Over Time
Activity Data Range: 2025 – 2026
Earliest Appearance: 27th June (in 2026)
Latest Appearance: 24th August (in 2025)
This chart presents a time-series summary of recorded observations. It is based on available records at the time of analysis and will evolve as further data are added. The rolling mean provides a smoothed representation of variation in recorded activity over time. Annual record totals are shown for context; years with fewer records may provide a less complete representation of activity than years with higher recording intensity. Interpretation should consider that apparent trends may reflect both biological change and variation in recording effort.

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.
