Two interesting papers that were held over for a year from The Hertfordshire Naturalist 2020 are now available online as a pdf download.

Dr Ronni Edmonds-Brown describes how varying techniques used to produce life-history tables for caddisflies (Trichoptera) have cast new light on their ecology and conservation requirements. And Dr Chantal Helm reports on the Hertfordshire Barbastelle Project and the recent exciting discovery of a maternity roosting colony of these conservation 'Red Listed' bats at Hitch Wood.

Both papers will appear in print in The Hertfordshire Naturalist 2021.
