Following a suggestion at a previous Monmouthshire Moth and Butterfly Group AGM, I analysed the Gwent record sets in terms of 1km by 1km (1km2) squares. There are 1628 1km2 squares falling wholly or partly within Gwent. The highest species total for a single square is 456 macrolepidoptera (butterflies plus macromoths), but there are 425 squares (26% of the total) with no butterfly or macromoth records at all.

The complete analysis is set out in the document linked below. Hopefully people will be able to start recording in some of the "zero squares" to help fill in the gaps.
