Factors affecting body size and fat content in a digger wasp

Oecologia, 2000
Body size is one of the most important life history traits. In mass-provisioning solitary Hymenoptera, the maximum attainable adult size is not under the control of the larva but is limited by the amount of resources provided by the mother. I investigated the effect of the amount of different maternal resources and potentially interfering abiotic ...

Nonrandom Provisioning by the Digger Wasp, Palmodes laeviventris (Hymenoptera: Sphecidae)

Annals of the Entomological Society of America, 1983
Predation strategies of Palmodes laeviventris (Cresson), a predator of Mormon crickets, are described. Prey taken are compared with prey available. Although mean prey sizes are no larger than the population means, a positive correlation between wasp size and prey size indicates that females do take large prey but are limited by their own body size ...

Female size affects provisioning and sex allocation in a digger wasp

Animal Behaviour, 1997
Investment ratios in field populations of the European beewolf, Philanthus triangulum F. (Hymenoptera, Sphecidae), are strongly biased towards males. Possible explanations are conditional sex allocation and/or constraints on provisioning females: daughters need at least three prey items (honey bees), whereas sons need only one to develop and reproduce.

Avian kleptoparasitism of the digger wasp Sphex pensylvanicus

The Canadian Entomologist, 2009
AbstractKleptoparasitism (one organism stealing prey from another) is especially common in birds. Avian kleptoparasites should be especially likely to target insects such as digger wasps (Hymenoptera: Sphecidae) that occur in large aggregations and repeatedly deliver large prey to the same nesting site.

Notes on the Habits of a Digger Wasp and Its Inquiline Flies.

Annals of the Entomological Society of America, 1930
One fine day in early April I noticed a large, steely blue wasp running awkwardly along the ground on tip toes. It was carrying a full grown cutworm, longer than itself, which it straddled and held in its mandibles. I had read something of the habits of the digger wasps, as written by Fabre, the Peck-hams, and others, and as this occurrence was taking ...

Communal Nesting in the Digger Wasp Cerceris australis (Hymenoptera : Sphecidae)

Australian Journal of Zoology, 1982
Study of 39 nests of Cerceris australis at nine localities in eastern Australia has demonstrated that most nests are occupied by two or three successive generations of wasps and may ultimately contain well over 100 cells. Nests are dug deep in the soil and are provisioned with scarab beetles, which are allowed to accumulate in the burrow before from ...

Do digger wasps time their provisioning activity to avoid cuckoo wasps (Hymenoptera: Crabronidae and Chrysididae)?

acta ethologica, 2010
Strategies adopted by parasitoids and kleptoparasites co-evolve with the defensive adaptations of their hosts, and vice-versa. Hedychrum rutilans and Hedychrum nobile are brood parasites of, respectively, Philanthus triangulum and Cerceris arenaria, two digger wasps that share most aspects of their nesting biology (solitary females dig aggregated nests

Observations on the Nesting Habits of Some Digger Wasps (Sphecidae: Hymenoptera)

Annals of the Entomological Society of America, 1945
I wish to express my appreciation to Dr. H. A. Scullen of Oregon State College for determining the three species of Cerceris , to Dr. Don Murray for determining the two species of Sphex , to Dr. H. J. Reinhart of the Texas Agricultural Experiment Station for his determinations of the Diptera, and to J. N. Knull and Mrs. D. J.

The Life-History and Habits of the Digger-Wasp Ammobia pennsylvanica (Linn.)

American Midland Naturalist, 1938
Peter Collinson (1749) reported to the Royal Society of London the habits of the "Great Black Wasp" of Pennsylvania, as communicated to him by John Bartram of Philadelphia. The drawings of the wasp and of her "large green grasshoppers" leave little doubt that they represent Ammobia pennsylvanica and her katydids, the first solitary digger-wasp of ...
