Median-joining haplotype networks of the available COI sequences of widespread bumble bees from Kolguev Island and other Arctic areas A Bombus balteatus B B. lapponicus C B. pyrrhopygus. The circle size is proportional to the number of available sequences belonging to a certain haplotype (smallest circle = one sequence). The small red dots indicate hypothetical ancestral haplotypes. Red numbers near branches indicate the number of nucleotide substitutions between haplotypes.
