Despite seemingly ideal conditions last year, several recorders reported lower than expected levels of dragonfly activity.
I've previously posted here the results of analysis of systematic records from Marsh Wood Pond near Wallingford (made by Julian Edwards) and also daily exuviae counts made by Deborah Dunn at her small garden pond. Since then I've also looked at Julian's records from nearby Cholsey Marsh as well as the transect surveys organised BBOWT at their two special Cothill reserves, Dry Sandford Pit and Parsonage Moor.
At the recent BDS on-line Spring meeting, I gave a talk looking these records and examining what they showed for numbers of dragonflies in 2025 compared with earlier years. It is notable that three of four sites showed declines in 2025 relative to 2024, with two sites down to 40% of their 2024 values.
