Amblycera
Amblycera is a parvorder of chewing lice from the infraorder Phthiraptera. The lice are ectoparasites and spend their entire lives parasitizing their hosts. Amblycera tend to mostly feed on birds, and have specialized anatomy to assist in feeding. The lice undergo a three part process of metamorphosis and survive around thirty days after moulting into an adult. They rely on a combination of skin debris and blood for nutrients to sustain themselves. Amblycera are distributed globally, and are very host–specific.
Species
Amblycera es un gran suborden de piojos masticadores, parásitos de aves y mamíferos. Amblycera es considerado el suborden de piojos más antiguo. Índice 1 Descripción 2 Familias 3 Especies significativas 4 Referencias Descripción Estos insectos son muy parecidos a los piojos chupadores avanzados, excepto que no permanecen en su huésped permanentemente. Vagan libremente sobre la superficie de su huésped y, a diferencia de otros piojos, no forman uniones permanentes. Se alimentan masticando áreas suaves de la piel, causando una zona de sangrado localizado del cual beben. Las especies de este suborden tienen antenas, pero no es fácil observarlas porque se encuentran en surcos en el costado de la cabeza. Por lo general, las antenas del suborden Amblycera poseen 4 o 5 segmentos. En cambio, pueden tener palpos maxilares y estos pueden ser visibles en muestras montadas pero pueden confundirse con las antenas. Los palpos de los amblyceranos tienen entre dos y cinco segmentos. Las mandíbulas de este suborden muerden horizontalmente. La cabeza es a menudo más ancha y redondeada anteriormente que la de Anoplura, pero esta diferencia morfológica no es confiable.

== Classification == Amblycera is currently classified as a parvorder, and it was named by Kellogg in 1896. Amblycera belongs to the infraorder Phthiraptera, which contains all lice, and is part of the larger order Psocodea, which also contains booklice, barklice and barkflies. Around 30% of all bird lice belong to Amblycera. A cladogram showing the position of Amblycera within Phthiraptera and Psocodea is shown below: {{clade| style=font-size:85%; line-height:100% |label1=Psocodea |1={{clade |1={{clade |label1=Troctomorpha |1={{clade |1= |2=Amphientometae }} |label2=Psocomorpha |2= }} |label2=Trogiomorpha |2= }} }}
