We found the largest measured genome size of all insect species so far in the species Bryodemella tuberculata (Caelifera: Acrididae) - 1C = 21.96 pg (21.48 gBp). Orthoptera species with 2n = 16 and 2n = 22 chromosomes have significantly larger genomes than species with other chromosome numbers, as they range from 1C = 1.37 to 21.96 pg. Reconstruction of ancestral genome sizes based on a phylogenetic tree of mitochondrial genomic data indicates that the ancestral genome size for Orthoptera is approximately 6.19 pg.
