Sizes of ladybug species vary, with the majority of species having a length between 0.8 and 18 millimeters. The size of a ladybug can vary depending on its species, age, and surroundings. Larger spots are typical of larger species, which can be a helpful identifying trait. The characteristic spot pattern on a ladybug's elytra, or hardened wing covers, aids in identifying the species. The patterns of ladybugs can be very different, ranging from perfectly spaced spots to haphazard clusters or even no spots at all. The arrangement and quantity of dots are crucial traits that set many species apart. (ladybug anatomy - 2021)
