1. CamouflageCaterpillar resemble thesurrounding environment to avoidbeing spot by predatorsCaterpillar of Comma Butterflyresemble bird dropping to avoidbeing prey by birds
2. PoisonousThe caterpillar extracts the toxinfrom their host plant (the plant theyeat)and process it into their own venom.Lonomia obliqua and Lonomia achelous arecaterpillars in Brazil that produce toxin that can causesevere internal hemorrhage and death in human after24 hours.The death rate caused by these caterpillars is 2.5%.
3. BehaviorAmorpha juglandis makes high pitchedwhistles ranging from 9 kHz to 22 kHz toscare away predatorsThe whistle last for 44 to 2060 ms andcomprise of 1 to 8 whistles.
