Caterpillars are the larval form of several insect groups, including moths, butterflies and sawflies. Many are colourful and ornamented with hairs and projections, usually signifying that they are are toxic to birds, their main predators. Other species are camouflaged, usually green or brown, to avoid detection.

Useful Websites and Publications
https://lepiforum.org/ - whilst it is in German it has an excellent series of images of both adults and caterpillars so useful if you have a candidate species in mind.
Several of the websites and social media sites dedicated to moths, butterflies and sawflies cover caterpillars as well.
Field Guide to the Caterpillars of Britain and Europe (Collins Field Guide) - includes moths and butterflies. Illustrations are not the best but it does usefully group caterpillars by their food plants.
