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. .....................
