Mine Comment:
The larva feeds exclusively on the leaves and leaf stalks (petiole) of aspen (Populus tremula and Populus tremuloides). The larva initially bores into and galls the petiole before moving into the leaf blade. It creates a triangular full depth blotch mine extending from the midrib. Frass is deposited along the midrib and lateral vein creating a V-shaped frass-line.
“Green Island” Phenomenon: The most notable characteristic of this species is that the area of the leaf mine often remains green even after the surrounding aspen leaf has turned yellow and fallen in the autumn. This “green island” helps identify the moth’s presence in fallen leaves.

Changes in First and Last Recorded Activity Dates Over Time
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 five-year moving average provides a smoothed representation of variation in recorded adult and immature activity over time, helping to illustrate longer-term trends in the earliest and latest recorded dates.
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.
Note: Clicking either the Adult Range.... or Immature Range... legends allows you to hide them, to show more discrete data.

If the Map Layers function fails, just refresh the page and it should be OK after. Use the +- zoom on the top left, or on a tablet, use two fingers to zoom. Remember, the last layer you ticked is the one which displays the popup information - they sit on top of each other - de-select then re-select, to see the popup values.
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.
