The question of whether farmed insects are sentient and capable of suffering is one of the most contested frontiers in animal welfare science.
The insect sentience question is consequential: if insects can suffer, the scale of insect farming makes this one of the most significant welfare issues in food production. Current scientific opinion is divided but increasingly precautionary. Some researchers argue that insect body size and nervous system structure make rich subjective experience unlikely; others point to behavioral evidence of aversive states that warrant precaution. The uncertainty itself is a reason to take the question seriously.
