Cockroaches and maggots aren't the most endearing creatures out there but they may be the best beasties at converting an invasive seaweed found around Spain into useful compost, according to Spanish researchers. They tested the ability of a range of creepy crawlies to break down the seaweed pest, Rugulopteryx okamurae, and found cockroaches (Eublaberus) and black soldier fly maggots (Hermetia illucens) were better at composting the seaweed than earthworms (Dendrobaena veneta) and mealworms (Tenebrio monitor). Harnessing the abilities of these underappreciated creatures offers promise for the development of 'circular economy' composting enterprises, the authors conclude.
