How does the coloration of B. fernaldii males typically compare to that of the queens?

Answer

Males often exhibit more pronounced yellow coloration than the queens

While the queen's appearance often trends toward paler yellow hair, especially on the pileum and thorax, the males of *B. fernaldii* frequently display even more intense or pronounced yellow coloration than the queens do. This contrasts with the workers, who tend to strongly resemble the workers of the specific host species they invade, often leading to identification challenges for observers focusing on general color patterns rather than leg structure.
