General comments:
Widespread but rather local in Hertfordshire.
Absent from most of Middlesex apart from in the extreme north west.


Hertfordshire Notes: This moth is probably under-recorded, because it rarely travels far and so is poorly represented in light trap catches in gardens; a light trap placed thirty or so feet from a Beech tree may not attract any Barred Hook-tips whilst a light placed closely against the trunk of the same tree may catch several. Although adults do come to mercury vapour lights, actinic traps may work better and I have, for example, recorded large numbers of the moth in Bishops Stortford Cemetery by placing an actinic trap at the base of one of the trees that line the road behind a brick wall - just a few inches from the passing public on their way home from the pub! A record from 'Tring, woods near Ashridge House', on 11th June 1887 by A. E. Gibbs in Transactions of the Hertfordshire Natural History Society and Field Club : l [= Roman 50]) appears likely to fall on the Buckinghamshire side of the border and so our earliest Hertfordshire record is that from Watford made by S. H. Spencer in 1895.

Middlesex Notes:
Extremely local; confined to the north-west of the county. Likely to extend eastwards via the North London woodlands to the Lea Valley but if so will probably be found only very locally.
