Insect cooking oil, insect butter and fatty alcohols can be made from such insects as the superworm (Zophobas morio). [199] Insect species including the black soldier fly or the housefly in their maggot forms, and beetle larvae such as mealworms , can be processed and used as feed for farmed animals including chicken, fish and pigs.
