Sphex ichneumoneus

provided by wikipedia EN

Sphex ichneumoneus, known commonly as the great golden digger wasp or great golden sand digger is a wasp in the family Sphecidae. It is identified by the golden pubescence on its head and thorax, its reddish orange legs, and partly reddish orange body. This wasp is native to the Western Hemisphere, from Canada to South America, and provisions its young with various types of paralyzed Orthoptera.[1]

D. Hofstadter cites the observation by Woodridge of S. ichneumoneus continually repeating behavior (checking a burrow before pulling in a cricket) as an example of genetic determinism, calling the behavior "sphexish".[2]

Sphex ichneumoneus (en anglais : great golden digger wasp, le Grand sphex doré) est une espèce américaine de guêpes fouisseuses appartenant au genre Sphex.

Description

Reproduction

Les femelles de Sphex ichneumoneus ne chassent que de grosses sauterelles vertes. Lorsqu’une proie est capturée, elles la paralysent à l’aide de leur aiguillon. La guêpe place ensuite sa victime dans une cellule préalablement construite, puis elle pond un œuf sur sa proie et referme la cellule. Les autres cellules sont remplies de la même façon, avec un œuf dans chaque cellule. À leur éclosion, les larves se nourrissent de la proie paralysée que leur mère leur a laissée. Ces proies, toujours bien vivantes, constituent un repas frais et nutritif pour ces futures guêpes.
