Which book would members of urg recommend which would not only identify
caterpillars, moths and butterflies but even more importantly, recommend and
identify their food sources?

D J Carter and B Hargreaves 'A Field Guide to Caterpillars and Moths in
Britain and Europe' pub Collins 1986, ISBN 0 00 219080 X

Colour plates of caterpillars by foodplant, with pictures alongside
accompanying text showing what the adult butterfly/moth looks like, has
a general index and a foodplant index.

It's brilliant for identifying caterpillars, and the foodplant lists at
the back will tell you which plants to grow to provide food for the
caterpillars.

Also has a useful plate of 'larvae of insects often confused with
caterpillars' - Solomon's Seal sawfly and the rest.
