Morley’s Final Catalogue: Not observed since 1890, when it was sometimes found to swarm around plants of vipers-bugloss at Brandon in July (Barrett), till 1925 at Worlington when it was plentiful, as also it was in 1933 at Euston (Whit).

Recent Status: Occurs along the coast and in Breckland.

Life Style: A single brooded species flying during May, June and July. The larvae feed inside the stems of Echium. They pupate in the stem.

Identification: The moth shape and resting posture is important for identification. There is a second species in the genus that is rare and occurs in similar habitats that has not been recorded in Suffolk. That species, T. balteolella, has a prominent pre-tornal spot or fascia rather than the slight one for T. ocnerostomella.
