. He conducted a range of experiments on the colours of polymorphic caterpillars to examine if food, background or other factors are involved in their colour changes. He was able to show that the caterpillars were sensitive to the background colours and that it was perceived even when they were blinded, and was among the earliest to suggest extraocular photoreception. Poulton enlarged the Hope entomological collections with his catches in the field which earned him the nickname of "Bag-all" Poulton. Many of the specimens are unmounted and held in biscuit tins. In his 1896 book ''Charles Darwin and the Theory of Natural Selection'', Poulton described Darwin's ''
