Invertebrates including butterflies, beetles, bees, and earthworms make up the majority of animal biodiversity, with emerging discussions about their welfare needs and conservation significance.
Wild invertebrate welfare is an emerging frontier that intersects conservation biology with animal welfare philosophy. The practical actions that benefit invertebrate populations - habitat creation, pesticide reduction, and organic farming support - simultaneously serve potential welfare interests and ecological function. Regardless of how debates about invertebrate sentience resolve, the ecological importance of invertebrates makes their conservation a priority that aligns welfare precaution with environmental benefit.
