Ancistrocerus



Clase:Insecta
Orden:Hymenoptera
Suborden:Apocrita
Superfamilia:Vespoidea
Familia:Vespidae
Subfamilia:Eumeninae
Genero:Ancistrocerus
Especie:?
La subfamilia Eumeninae (Hymenoptera: Vespidae) es cosmopolita, posee 3000 especies y 203 géneros (Willink, 1998). Hasta hace pocos años poseía categoría de familia, dividida en tres subfamilias: Eumeninae y Zethinae con distribución cosmopolita, excepto en Nueva Zelandia y Raphidoglossinae que se distribuye en Europa y África (Richards, 1962). Estudios filogenéticos realizados por Carpenter (1982) llevaron a unirlas en una sola subfamilia Eumeninae (Willink, 1998).Son avispas solitarias, en algunos casos gregarias. Todas son predadoras, en general de larvas de lepidópteros, aunque también alimentan a sus crías con larvas de coleópteros o himenópteros símfitas; los adultos visitan flores. Todas construyen sus nidos, para los que generalmente utilizan barro. Algunas construyen nidos aislados, generalmente en forma de odre, otras utilizan rendijas o cavidades en las rocas, madera o en cavidades preexistentes; algunas utilizan nidos de otras avispas y también hay especies que cavan sus nidos en el suelo.fuente:http://www.scielo.org.ar/scielo.php?script=sci_arttext&pid=S0373-56802005000200003&lng=en&nrm=iso
English:
Potter wasps (or mason wasps) also known as Dirt daubers are cosmopolitan wasps that are typically treated as a subfamily of Vespidae, but have in the past sometimes been recognized as a separate family, Eumenidae. They are the most diverse subfamily of vespids, with over 200 genera, and contain the vast majority of species in the family; all known eumenine species are solitary predators. Most species are black or brown, and commonly marked with strikingly contrasting patterns of yellow, white, orange, or red (or combinations thereof). Like most vespids, their wings are folded longitudinally at rest.Potter wasps are named for the nests they construct out of mud and water, and these can have one to multiple individual cells. When a cell is completed, the adult wasp typically collects beetle larvae, spiders or caterpillars and, paralyzing them, places them in the cell to serve as food for a single wasp larva. In a few species, the adult wasp lays a single egg in the opening of the cell, suspended from a thread of dried fluid. When the wasp larva hatches, it drops and immediately feeds upon the larvae, and later breaks out of the nest to begin its adult life. Adult potter wasps feed on plant nectar. It is believed that Native Americans based their pottery designs upon the form of local potter wasp nests. [von Frisch, 1974]fuente:http://en.wikipedia.org/wiki/Potter_wasp
