Hi Kifaru,
Thanks for the kind words,much appreciated.
The Universities of London and York are involved in the project I mentioned; unfortunately, no zoos of which I'm aware (but I've not done a thorough check).
Re smaller creatures, I feel much the same., Here in the US, insect-keeping is still in it's infancy. I've set up a few invert exhibits for the Bronx Zoo, but, except for a summer butterfly aviary, there is still no major invert exhibit!
Japan is the place for zoogoers who enjoy insects; the Tama Zoo blew me away - a giant insect house and an outdoor insect aviary that was larger than those most zoos devote to birds!...others just as impressive.
Best regards, Frank
