The Monmouthshire dragonfly list

The table below lists the 33 species of dragonfly which have been reliably recorded in Monmouthshire.  Some of these are rare visitors to the county: records of these are of particular interest, and can be added to our county database if supporting evidence is provided, such as a photograph or some notes describing what was seen and how more common lookalike species were ruled out. Some of our resident species are usually only found in certain areas of the county and so supporting evidence is asked for if these are seen outside their usual areas.

One further species, Banded Darter Sympetrum pedemontanum, was found in 1995 near Tredegar, and listed in several publications as being seen within Monmouthshire. Research for an account of this occurrence led to the realisation that it spent its time wholly within Breconshire, so unfortunately this distinctive insect (the first, and as of 2022, the only, British record) is no longer on the county list. Single unconfirmed records each of two other species (Downy Emerald Cordulia aenea and Scarce Chaser Libellula fulva) were reviewed in 2020/2021 and no supporting evidence could be traced for either, so these have been excluded from the list. Subsequently (2023) further details of the putative Scarce Chaser (on the Blorenge in 1983) have come to light: photographs of it were examined shortly after it was reported, and it was a misidentified Broad-bodied Chaser.
