黄粉虫生命周期 幼虫 蛹阶段 特写 循环经济 自给自足 昆虫养殖

close-up reveals the writhing density of a live mealworm (Tenebrio molitor) larval colony burrowing through fresh wheat bran after cleaning and refeeding, a visible marker of a thriving, productive home sustainable farming system. Vegetable scraps provide moisture within the substrate, eliminating the need for any purchased inputs and keeping the system entirely zero waste. A pupa visible among the larvae signals the ongoing life cycle progression from larva to beetle, the reproductive stage that continuously replenishes the colony. Macro close-up shot, vertical.
