Caterpillar's smell test

Caption

Scientists from the National University of Singapore conducted smell tests with the caterpillars of the squinting bush brown butterfly, Bicyclus anynana, and found that caterpillars’ food preferences are determined by factors, or substances, present in their blood and these preferences could be passed on to offspring through the bloodstream.
