The seven-spotted lady beetle is carnivorous. Both the adult and larval stages feed on insects harmful to plants, such as aphids and scale insects (Anonymous 1997). Adults can be known to eat up to 100 aphids a day (Arnett Jr., et al 1980). Rather than using any complicated methods for eating its prey, the ladybug kills its prey outright and then devours it (Waldbauer, 1998).
