Since opening this thread I've read more of the book and Mr. Hoddinott does redeem himself, stressing that any harm or danger to any creature is not what photography is about, my words not his. After reading comments from others a link in the book that you may find interesting is
www.butterfly-conservation.org. There are some points of interest for all with an interest in insects, even where to go to raise your own. (Just remember a divorce is most expensive .)
Ive learned from this thread, so a big thank you to all that contributed.
Regards, Dean.
