Hertfordshire & Middlesex Moth Group
We are an informal group of moth enthusiasts in Hertfordshire(VC20) and Middlesex(VC21)(aka North London). See more about us by clicking on this page's header.

The map shows our area and its main towns, use it to put our distribution maps into context too.

This is a guide to the status of all the species recorded from our area. Maps are updated to include 2019 data, and if significant 2020.

The notes are largely based on publications listed here. Notes from Colin Plant's (our County Moth Recorder) 2008 book are now over a decade old and so may not always reflect recent trends, where there are significant changes these are gradually being added.

The flight charts, for species with sufficient adult data, are based on dated records, most from 2000 onwards.
