Animal behavior: A digger wasp never forgets

Current Biology
A study of wild digger wasps reveals they flexibly schedule parental care across multiple spatially distributed nests, remembering where, when, and what they have provisioned their larvae. Digger wasps can be a novel model for future neuroethological studies of insect memory.

A Signal Produced by a Digger Wasp Preying on Crickets

1990
Females of the digger wasp Liris niger hunt for crickets to provide food for their larvae. They search for crickets by running very fast on the ground. Crickets are able to detect the approach of the hunting wasps by their cercal filiform hairs which are sensitive to wind.

Influence of the reactions of the prey on the stinging patterns of digger wasps

Experientia, 1983
The degree of reactivity of the prey affects the form of behavior subsequently adopted in paralyzing the prey. The mechanism underlying this ontogenetic plasticity is discussed.

Hydrocarbons in the nest material of a solitary digger wasp represent a kairomone for a specialized cuckoo wasp

Animal Behaviour, 2008
Cuticular hydrocarbons (CHCs) can be found on the cuticle of insects and they primarily serve to reduce desiccation. Additionally, they constitute important cues for species, kin and nestmate recognition. In paper wasps, these CHCs can also be found on the nest material and facilitate nestmate recognition.

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.

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 ...

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 ...
