Hertfordshire Notes:
Widespread, but local.
The preferred habitat is blackthorn thickets and this may explain its absence from garden lists and from the entire of Middlesex? Although attracted to light it is primarily a dawn species, flying from first light to sunrise, which explains its absence from lists made on trips out, as most are ended well before dawn breaks.
