Several days after trapping the Privet Hawk-moth (above), we were then delighted to find a Pine Hawk-moth in the trap early one morning (pictured below) - a new species for the reserve this year, and one which isn't always annual.
As well as many species appearing in good numbers over recent weeks, we have also recorded several scarcer species for the reserve. During recent years we have recorded just singles of the rather stunning Oak Eggar moth, which is attracted to our light trap at Bank Island. However, this year we have already recorded six of these large and impressive moths. The Oak Eggar, surprisingly given its name, does not feed on Oak, but instead actually got its name from the fact that its cocoon is acorn-like in appearance. The food plants of the caterpillar are mainly Heather and Bilberry but also include Bramble, Willow and Hawthorn – the latter three of which are found around the NNR base at Bank Island.
