The boat trip was preceded by an excellent slide talk about the 16 species of bat seen in the UK delivered by a very knowledgable bat expert.
Unfortunately, the weather wasn't playing ball and what should have been a lovely summer's evening felt more autumnal with a cold wind prevalent. This put paid to seeing very much, the only moths caught included 2 Herbaceous Hebrew Characters but the organisers had caught some moths earlier in true Blue Peter tradition and they showed us ones they'd caught earlier. These included Garden Tiger, Dark Arches and 3 others which I can't recall the names exactly but may have been called something like Dark Longshanks and a yellow moth called something like Yellow Canary Surprise and Brass beauty. Update, 1/9/09 The actual names of these moths were Dark Swordgrass, Canary shouldered Thorn and Burnished Brass, thanks to Peter C for supplying me with the correct names.
These moths have wonderfully evocative names because they were originally given their names by Victorian clergy.
An exciting boat trip armed with ultrasonic bat detectors which clicked when a bat was near revealed about 15 Pipistrelles in flight but I did not see any obvious Daubenton Bats, oh well I'll have to try again next year.
