The mid-August moth night organised by Jono Forgham and members of the Herts Moth Group identified at least 120 moths of 30 species recorded in Birchanger Wood. The total was less than expected. However, there were two moth species identified that had previously not been recorded – the gypsy moth and the metalampra italica micro moth – which have expanded their range.
