I see that Butterfly Conservation have given the date for National Moth Nights 2009. They will be on Friday 18 and Saturday 19 September 2009.
Do you think that it might be possible to arrange a few trapping sessions across Calderdale to see what we get.
They have no specific species or habitats that they are targetting, however the theme is migration. Andy mentioned earlier that we might like to get the LNR lists of moths and butterflies up to date. (I'm still collating the various info on the different sites, but for many it is pretty sketchy), so one option is to do some trapping on one of these sites.
We may also (as the Council) run a public moth trapping event on one of these nights and publicise it in the Wildside guided walks and events programme, if anyone would be interested in helping out, especially with the identification then please let me know.
