RE..Tissue and heralds

Herald moths go into caves, tunnels, old mines and old buildings to hibernate and only in exceptional cases i.e. very cold snaps, will they move further into the cave. Tissues on the other hand do not hibernate but go into periods of torpor for a week or two but are active all winter. Heralds in a way are similar to bats and often are covered in condensation droplets; this will stop the body from dehydrating. I have been working on these two species for 10 years now and have picked up all sorts of things and am trying to write it all up so will keep you in touch. You ask if the Tissues feed and am currently working on this by analysing the condensation water in caves looking for carbon in the form of sugars and also the bacteria on the cave walls but it is a very slow job. If you send me an address I will send you a paper I did for a field day a couple of years ago if you like. I also think food plants may be other species as well as what is written in books, I have yet to find a caterpillar. Best wishes David. .....................
Many thanks to David hodson for this info

Bare head tunnel

Had another look in Bare Head tunnel today with Steve B and Charlie but no Tissue could be found.There were at least 14 heralds and i will be having another look over the weekend. The best thing about this record is it shows species recorded 100 years ago are still around if you look hard enough.There is still hope of finding Northern rustic and Brindled Ochre

Moth Whispering

Viewers of the Lord of The Rings trillogy of films and the recent Hobbit, may have seen the amazing 'moth whispering' abilities of the wizard, Gandalf. He uses his powers to send a message of help to the eagles via a moth. I have been trying to id this moth and a strong contender is the Emperor Gum Moth Opodipthera eucalypti . A New Zealand species (Where the filming was done). See pics of the moth on Gandalf's hand and the Gum Moth. Happy new year and Happy hunting in this mild spell (nothing here yet) Winston (Hebden Bridge)
