Journal of Hymenoptera Research 38: 135–139. doi: 10.3897/JHR.38.7763 Abstract Male behavior of Neotropical swarm-founding wasps has rarely been observed. The few published ob- servations about male activities only describe their behavior during the short period they spend inside nests. In consequence, virtually nothing is known about what they do outside the colonies, and even less is known about mating behavior. This paper provides the first report of Epiponini males arriving at a colony with virgin females. The behavior of males and workers after queen removal was observed in one colony of Chartergellus communis located at a farm in Pedregulho, São Paulo, Brazil. The day after queen elimination, males were observed outside the nest.

I am currently working on a review of vespid nest architecture and hope that I can contribute something toward resolution of the relationships of the various genera of the tribe Polybiini. After visiting the MCZ, AMNH and the USNM I conclude that there are rather few specimens of nests in the major museums and I am very interested in hearing from anyone who has photos or reliable notes on nests that are anomolous in form, placement, or otherwise depart from expectations. I am especially interested in seeing some nests or fragments of the brood region of any Polybioides or Parapolybia. Tarlton Rayment Again RAYMENT'S DRAWINGS - ACT 3 by Roger A.

  • Comparative Morphology of the Stinger in Social Wasps (Hymenoptera: Vespidae)
    insects Article Comparative Morphology of the Stinger in Social Wasps (Hymenoptera: Vespidae) Mario Bissessarsingh 1,2 and Christopher K. Starr 1,* 1 Department of Life Sciences, University of the West Indies, St Augustine, Trinidad and Tobago; [email protected] 2 San Fernando East Secondary School, Pleasantville, Trinidad and Tobago * Correspondence: [email protected] Simple Summary: Both solitary and social wasps have a fully functional venom apparatus and can deliver painful stings, which they do in self-defense. However, solitary wasps sting in subduing prey, while social wasps do so in defense of the colony. The structure of the stinger is remarkably uniform across the large family that comprises both solitary and social species. The most notable source of variation is in the number and strength of barbs at the tips of the slender sting lancets that penetrate the wound in stinging. These are more numerous and robust in New World social species with very large colonies, so that in stinging human skin they often cannot be withdrawn, leading to sting autotomy, which is fatal to the wasp. This phenomenon is well-known from honey bees. Abstract: The physical features of the stinger are compared in 51 species of vespid wasps: 4 eumenines and zethines, 2 stenogastrines, 16 independent-founding polistines, 13 swarm-founding New World polistines, and 16 vespines. The overall structure of the stinger is remarkably uniform within the family. Although the wasps show a broad range in body size and social habits, the central part of Citation: Bissessarsingh, M.; Starr, the venom-delivery apparatus—the sting shaft—varies only to a modest extent in length relative to C.K.

  • Insect Egg Size and Shape Evolve with Ecology but Not Developmental Rate Samuel H
    ARTICLE https://doi.org/10.1038/s41586-019-1302-4 Insect egg size and shape evolve with ecology but not developmental rate Samuel H. Church1,4*, Seth Donoughe1,3,4, Bruno A. S. de Medeiros1 & Cassandra G. Extavour1,2* Over the course of evolution, organism size has diversified markedly. Changes in size are thought to have occurred because of developmental, morphological and/or ecological pressures. To perform phylogenetic tests of the potential effects of these pressures, here we generated a dataset of more than ten thousand descriptions of insect eggs, and combined these with genetic and life-history datasets. We show that, across eight orders of magnitude of variation in egg volume, the relationship between size and shape itself evolves, such that previously predicted global patterns of scaling do not adequately explain the diversity in egg shapes. We show that egg size is not correlated with developmental rate and that, for many insects, egg size is not correlated with adult body size. Instead, we find that the evolution of parasitoidism and aquatic oviposition help to explain the diversification in the size and shape of insect eggs. Our study suggests that where eggs are laid, rather than universal allometric constants, underlies the evolution of insect egg size and shape. Size is a fundamental factor in many biological processes. The size of an 526 families and every currently described extant hexapod order24 organism may affect interactions both with other organisms and with (Fig. 1a and Supplementary Fig. 1). We combined this dataset with the environment1,2, it scales with features of morphology and physi- backbone hexapod phylogenies25,26 that we enriched to include taxa ology3, and larger animals often have higher fitness4.

Le niveaux modeste de l'organisation sociale démontrée par ces guêpes peut etre du au manque des matériaux nécessaires pour la construction de grands nids. Polistinae et Vespinae construisent des rayons suspendus d'une tige fine faite de papier dur et fibreux. Cette structure de rayons suspendus a évolué apparamment a cause de la prédation par les fourmis, mais la où les circomstances ont, par la suite, favorise une évolution sociale plus développée, les matériaux convenaient deja a la construction de nids plus grands. Dans la construction des nids de Stenogastrinae les cellules sont attachées directement au substrat, ce qui provient probablement de la mauvaise qualité du papier où de la lourdeur de la boue dont il s'agit dans leur construction. De tels matériaux ne conveniennent pas non plus a la construction de nids plus grands, tels qu'il faudrait pour abriter des colonies sociales plus évoluées. Mots-cles: Stenogastrinae, matériaux des nids, évolution social Summary: The social organisation of the Stenogastrinae is rather uniform while the design of their nests is very varied.

National Museum of Natural History Washington DC 20560 Notes from the Editor This issue contains a lot of research news, quite a few travel reports, two obituaries, information on the Oxford Museum Collection, and a variety of other material. Please keep sending me reports of your activities for inclusion in the next issue or else Sphecos will gradually diminish in size. There will be a gathering of hymenopterists from all over North America at the Annual Meeting of the Entomological Society of America at Toronto, Canada, this December. The purpose of this meeting is to establish a society and journal for hymenopterists. Your editor will attend; a summary of the meeting will appear in the next issue of Sphecos. In the last issue I listed the names of approximately 100 people who had not returned the Sphecos questionnaire, noting that they had been dropped from the active mailing list as a result. The response to this list was underwhelming - only a handful of people listed sent in the questionnaire - so my task of putting issues in envelopes and afixing mailing labels has been reduced by quite a bit. I would like to thank Vivian Spriggs for typing most of this issue of Sphecos. Research News/Help Needed 0. W. Richards (89 ST. Stephen's Road, Ealing, London Wl3 8JA), has four papers in preparation dealing with the following: vespid larvae, Arabian Masaridae, Arabian Vespidae, and corrections and additions to his "Social Wasps of the Americas".

Biologia Animale e Genetica, Univ. di Firenze, Centra per lo Studio delle Faunistica ed Ecologia Tropicaii del CNR, Firenze, Via Romana 17, 50125 Firenze, Italia SUMMARY Males of two species of stenogastrine wasps Parischnogaster mellyi and P. alternata observed in captivity perform patrolling behaviour. They also present anatomic and morphological structures which are probably related to this behaviour. The patrolling behaviour of P. alternata is described for the first time and is quite similar to that of P. mellyi (Turillazzi, 1983a and b) with hovering flights near landmarks and displays of white stripes on the abdominal tergites. The patrolling flights occur at different times of the day with respect to P. mellyi. Males of P. mellyi form unisexual clusters on thread-like substrata in nidification sites. Our data show that foundress females of same species probably use these clusters as indicators that the substratum is a potentially good one for nidification. KEY WORDS : Stenogastrinae, reproductive behaviour, tegumental glands, male clusters.

TESEO 1 and S. TURILLAZZI 1 1 Dipartimento di Biologia Evoluzionistica “Leo Pardi”, Università degli Studi di Firenze, Via Romana 17, 50125 Firenze, Italy 2 Institute of Biological Sciences, University of Malaya, 50603 Kuala Lumpur, Malaysia Received 1 July 2008, accepted 27 November 2008 The basic social biology and nest architecture of the social wasp Liostenogaster topographica Turillazzi 1999 were studied in Peninsu- lar Malaysia. This species shows the main shared characteristics of hover wasps (Vespidae Stenogastrinae), including the use of an abdomi- nal secretion in brood rearing and the presence on the nest of several females with developed ovaries. Colonies are small by the standards of social wasps but are probably the largest of any studied species of hover wasp. The nest has a peculiar architecture and the material used for its construction seems to be effective in keeping ants away from the perim- eter of the nest.

Baracchi et alii INTRODUCTION The Stenogastrinae, known as hover wasps, are a natural group of social wasps within the Vespidae, comprising about 70 described species in seven genera. The group is restricted to South Asia. The most generally accepted phylogenetic hypothesis (CARPENTER 1982, 1988; CARPENTER & STARR 2000) places them as the sister-group of the Polistinae + Vespinae, render- ing the social wasps as a whole monophyletic.
