General Comment: None
Flight Period: June /  July –  On the wing during the day and at night in June & July. Mine Period:  January /  February /  March /  April /  May /  July /  August /  September /  October /  November /  December
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: Not Recorded
Mine Feeding Method/s:  Case
Mine Comment: The larva feed on the seeds of White Clover forming a case from the floret and feeding until they are fully developed by early August. They hibernate on the ground in their cases over the winter re-appearing in the spring with the overall mining/feeding activity lasting until May.

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.
