Barred Tooth-striped
Trichopteryx polycommata
([Denis & Schiffermüller], 1775) 1880 / 70.201
Norfolk status
Breckland. Woodland, chalk downland and scrubby areas.

Barred Tooth-striped presence in the Norfolk Breck is remarkable because of the long distance that separates it from it's nearest currently occupied sites, in Kent and southeast England and in the Lake District.

First recorded from a single Breck site in 1980, annual surveys have produced further locations in the Brecks.
Best recorded by larval searches on wild privet in late May early June.

Barred Tooth-striped larva also host to the Parasitoid Wasp Earinus transversus. In a 2005 survey, 16/30 larvae were parasitised by E. transversus.
No other location for this wasp is known in the world!

Annual larval surveys by Gerry Haggett and others, regularly monitor the colonies in Norfolk.
