The series follows the adventures of Lloyd B Fly, a housefly and the middle child of 451. Lloyd lives with his parents, his little sister PB and their 224 maggot siblings inside a compost bin they call home. In the series, Lloyd and PB are usually accompanied by Lloyd’s best friend, Abacus Woodlouse, and eccentric tag-along, Cornea Butterfly. Together they explore the strange world beyond the compost bin, where there is no shortage of lessons for Lloyd to very nearly learn.
