35.001 Aproaerema sangiella (Stainton, 1863)
Status and Distribution
Very local, with a scattered distribution mainly centred around parts of south-east and northern England, the east side of Scotland and western Ireland. Apparently absent from Wales, Isle of Man and the Channel Islands. Only 39 records known nationally between 1999 and 2023, but with no indication of any significant change in distribution.
A record from VC60 (Gait Barrows NNR) on 10.7.1999 detailed in the Entomologist's Rec. 112: 198 was a misidentification. A record from Dorset in 1967 has been listed in the county fauna but is, subject to further details, considered unconfirmed.

Habitat
Finding the Moth
Larva: feeds in spun leaves usually at the tips of the stem with a suggested preference for fleshier leaved plants.
Adult: can be swept from amongst the foodplant, has been observed resting on the plant during the day and is attracted to both actinic and mercury vapour light.
Similar Species
When fresh this species has a purplish or bluish tinge to the forewing with some scattered creamy-white to yellowish scales particularly beyond the blackish stigmata. The presence of a creamy-white to yellowish costal patch at three-quarters and similar tornal patch can occasionally extend to form a broken fascia. There is a prominent creamy-white stripe above the eyes and the pale inner surface of the second segment of the labial palps stand out well. There is no hint of any pale lining on the underside of the forewing as in A. taeniolella. It superficially resembles Aproaerema anthyllidella and Eulamprotes immaculatella from which it is readily separated by its larger size and broader wings. It may be necessary to dissect if there is any doubt or if the moth is at all worn.
Single brooded from late May to early September.
