It was in June 2020 and as part of my PhD thesis research, I was doing an experiment on plant-insect interaction, particularly looking into how silicon nutrient supply confers grass resistance against subsequent herbivores. To address this question, I exposed grass to caterpillars (Helicoverpa armigera) for six days after which I removed them and again infested the same host plant with house crickets (Acheta domesticus). But, I kept some plants inoculated with both herbivores. Two days later, I never thought of what am I witnessing, seeing that some caterpillars already started to eat crickets in favor of grass leaves! I pulled out my mobile phone from my pocket and started recording the show (video attached here), just being curios about such incidents, where the stronger man can fed on the weaker ones despite the availability of food for both insects. One of those mysteries question was why caterpillars feeding was so outrageously complex? I tried to search an existing knowledge that can either prove or disprove this behavior but couldn't able to find any support. Instead I said "My armyworm is special cos when he feels threatened he did everything to defend himself from enemies and his arms turn into sword to capture the weaker enemies and his teeth cut enemies gut into pieces."
