How are male Christmas beetles often distinguished visually from the females of their species?
Answer
By possessing small projections or horns on the front of their heads
Sexual dimorphism is a noticeable characteristic within the adult Christmas beetle population. Specifically, the males possess morphological features on their heads that are absent or less pronounced in females. These distinguishing features are described as small projections or horns located on the front of the head capsule. These structures likely play a role in intraspecific interactions, such as competition or mating rituals. Identifying this cephalic feature is the key physical difference mentioned for telling the sexes apart, beyond potential slight variations in coloration or overall size when observed closely.
