The record holder, measuring 62.4 cm (24,5 in), is a representative of Spectra order. This specimen can be admired in the Chinese museum in Chengdu. Spectras are among the largest insects on Earth. In contrast, the smallest insect is the parasitic dragonfly Dicopomorpha echmepterygi, whose females (and they are more than half the size of the males) measure 550 μm (0.55 mm).
