The Nesting Of A Carpenter Bee, Wilmatte Porter Cockerell Oct 1903

The Nesting Of A Carpenter Bee, Wilmatte Porter Cockerell

Co

About the middle of August when the flowers are at their best in our mountain canyon (Beulah, New Mexico), and the wild bees and butterflies have a daily surfeit of nectar, this clever little carpenter goes to work to make a storehouse and to provide for the young of the next generation. Many bees and wasps make their nests by cutting out; burrows in trees and bushes, but few work as quickly and skillfully as Clisodon terminalis.

Classification Of The Fossorial, Predateous And Parasitic Wasps, Or The Superfamily Vespoidea No.13, William H. Ashmead Apr 1903

Classification Of The Fossorial, Predateous And Parasitic Wasps, Or The Superfamily Vespoidea No.13, William H. Ashmead

An

This family, although quite distinct, is closely allied to the two which follow-the Myrmosidae and the Mutillidae-and it will probably be difficult for the student to separate at once the wingless females from some in the families mentioned. Some authorities, having been unable to find good characters to separate these wasps, have classified all together as a single large family under the name .Mutillidae; but I think incorrectly so.

Classification Of The Fossorial, Predateous And Parasitic Wasps, Or The Superfamily Vespoidea No.12, William H. Ashmead

An

By most systematists this family is still classified with the Scoliidae, although separated as a distinct family by the Swedish entomologist, C. G. Thomson, as early as 1874. I agree with Thomson, and believe these wasps form a distinct family, easily recognize d by the characters made use of in my table of families.

Monographie Des Guepes Ou Vespa, R. Buysson Jan 1903

Monographie Des Guepes Ou Vespa, R. Buysson

Bu

Les Hymenopteres don’t il est question dans cette etude appartiennent au genre Vespa, lequel fait partie de la famille des Vespides. Ceux-ci terminent un des rameaux de l’arbre philogenetique des Hymenopteres, don’t le tronc est forme par ces insectes don’t les larves purvoient ells-memes a leur nourriture et vivent de matieres vegetales. Au fur et a mesure que l’on s’eleve de la souche aux rameaux, on reconnait que l’instinct s’est modifie avec la maniere de vivre.
