Bald-faced hornet coloring differentiates it from its mostly black and yellow genus mates. Baldfaced hornets are distinguished from other yellowjackets by their white and black coloring. It has a white or "baldfaced" head, which is the source of its colloquial name. These wasps also have three white stripes at the end of their bodies. They are notably larger than other species of "Dolichovespula", as adults average about in length. Queen and worker wasps have similar morphologies. However, workers are covered by small hairs while the queen remains hairless. Queens are always larger than workers in their colonies, though size distributions can vary
Bare-faced bulbul Bare-faced bulbul The bare-faced bulbul ("Nok hualon") is a member of the bulbul family of passerine birds. It was newly described from central Laos in 2009. It is one of the very few Asian songbirds with a bald (featherless) face and is the first new species of bulbul to be described from Asia in almost a century. The species epithet "hualon" is from the Lao word for "bald-headed". A 2018 molecular phylogenetic study of the bulbuls suggested that the species does not fit in the clade containing the core "Pycnonotus" and stood apart suggesting its placement in a new genus
