Steeple Aston - Southern Hawker emergences in 2022

Deborah Dunn has had a very productive year for her daily monitoring of Southern Hawker emergences and exuviae at her small garden pond. This year she counted a remarkable total of 60 exuviae, spread out over an extended period from 29 June to 1 August. She also recorded 12 live emergences. 

The plot below shows the daily exuviae counts for comparison with 2020 and 2021. The 2022 total of 60 was by far the highest of these three years and this year was the most extended season so far.
