Caterpillars retrieve 'voicemail' by eating soil: Plant legacy affects aboveground insects through soil

Info

Leaf-feeding caterpillars greatly enrich their intestinal flora by eating soil. It's even possible to trace the legacy effects of plants that previously grew in that soil through bacteria and fungi in the caterpillars. Researchers of the Netherlands Institute of Ecology (NIOO-KNAW) have just published these findings in the journal Nature Communications.
