Taxonomy:   Macro   >>  Sesiidae  >> Sesiinae

Distribution:  (First record: 1863 at Overseal, Swadlincote )  –  (Last record: 1983 / 1984 at Spring Wood, Brierley Wood )  –  A resident species that is uncommon and under recorded. In 1988 it was described as locally common. Favours heathland and woodland where Birch (Betula) occurs and also favours three year old birch stumps after cutting. A localised species requiring specific habitat, which is probably the reason why there are no modern day records of this moth. The use of Pheromone lure in suitable birch woodland may produce results.

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.
