Nesting of a rare eumenine wasp, Paragymnomerus signaticollis tauricus, was observed in the Crimea. Females of this species inhabit untilled steppes and nest in clay loam soil. The nests are vertical burrows 55-120 mm deep and 7-9 mm wide, surmounted by more or less curved turrets that open sideways. The nests contain 1-4 cells and have either linear or branched structure. The cells are of the same width as the other parts of nest burrow and are 13-23 mm long. The species is univoltine; prepupae hibernate in the cocoon for one or two years...

The genus Ahermodontus Báguena, 1930 (Coleoptera: Scarabaeidae: Aphodiinae) is currently comprised of three species: A. marini Báguena, 1930 and A. ambrosi (Pardo Alcaide, 1936) from southern Spain and Morocco and A. bischoffi (Všetečka, 1939) from Albania (see e.g., Dellacasa et al. 2001, 2002, 2016). The distribution and bionomy of both of the western Mediterranean Ahermodontus species are relatively well known. Contrastingly, A. bischoffi was described using a single female specimen collected by A. Bischoff in Llogara, Albania in 1934 (Všetečka 1939) and additional specimens remained unknown until now...

An illustrated key to the currently recognized genera of the subfamily Eumeninae (Vespidae) from China is presented together with a list of 267 species and subspecies, belonging to 51 genera. Nortozumia van der Vecht, 1937 is reported for the first time from China. Two replacement names are proposed for junior primary homonyms: Ancistrocerus rufofrustius Tan & Carpenter, nom. n. replacing Ancistrocerus rufopictus (Kostylev) and Orientalicesa confasciatus Tan & Carpenter, nom. n. replacing Orientalicesa unifasciatus (von Schulthess, 1934)...

Swarm-founding 'Warrior wasps' (Synoeca spp.) are found throughout the tropical regions of South America, are much feared due to their aggressive nest defence and painful sting. There are only five species of Synoeca, all construct distinctive nests that consist of a single sessile comb built onto the surface of a tree or rock face, which is covered by a ribbed envelope. Although locally common, research into this group is just starting. We studied eight colonies of Synoeca septentrionalis, a species recently been described from Brazil...

Many social insect species produce signals that either recruit foragers to a specific food source or simply activate more nestmates to become foragers. Both are means of enhancing resource exploitation by increasing the number of individuals devoted to gathering profitable resources. Gastral drumming (GD) has been documented in several species of yellowjackets and hornets (Vespidae: Vespinae). It has been hypothesized that it is a hunger signal, but there is little empirical evidence to support this claim. An alternative hypothesis is that GD recruits workers to forage for food...

Swarm-founding wasps are endemic and common representatives of neotropical fauna and compose an interesting social tribe of vespids, presenting both complex social characteristics and uncommon traits for a eusocial group, such as the absence of castes with distinct morphology. The paper wasp Protonectarina sylveirae (Saussure) presents a broad distribution from Brazil, Argentina and Paraguay, occurring widespread in the Atlantic rainforest and arboreal Caatinga, being absent in the Amazon region. Given the peculiar distribution among swarm-founding wasps, an integrative approach to reconstruct the evolutionary history of P...

Consistent differences in behavior between individuals, otherwise known as animal personalities, have become a staple in behavioral ecology due to their ability to explain a wide range of phenomena. Social organisms are especially serviceable to animal personality techniques because they can be used to explore behavioral variation at both the individual and group level. Despite the success of personality research in social organisms generally, and social Hymenoptera in particular, social wasps (Vespidae) have received little to no attention in the personality literature...

A wide variety of abiotic and biotic factors act on insect pests to regulate their populations. Knowledge of the time and magnitude of these factors is fundamental to understanding population dynamics and developing efficient pest management systems. We investigate the natural mortality factors, critical pest stages, and key mortality factors that regulate Chrysodeixis includens populations via ecological life tables. The total mortality caused by natural factors was 99.99%. Natural enemies were the most important mortality factors in all pest stages...

Three new species of the genus Symmorphus Wesmael, 1836 are described with materials from South Korea and Far eastern Russia: Symmorphus kurzenkoi Kim sp. nov., S. truncatoclypeus Kim sp. nov., S. yamanei Kim sp. nov. All are members of the subgenus Symmorphus Wesmael 1836. S. kurzenkoi Kim sp. nov. is likely to be closely related to Symmorphus fuscipes in having well developed and completely closed propodeal submedian carina, but is clearly different from the latter in the shape of metasomal tergum 1 that is not markedly narrowed toward base...

This study provides the first annotated check list of the Vespidae of Pakistan. It is based on the National Insect Museum collection and various studies in Pakistan. Among 105 identified taxa, 77 species and 28 subspecies are recorded in the four subfamilies Eumeninae, Masarinae, Polistinae and Vespinae. Three new records for the fauna of Pakistan are added, namely Anterhynchium mellyi, Antepipona ovalis and Eumenes coronatus coronatus. Among the total, 12 species/subspecies are endemic to Pakistan, namely Ancistrocerus pakistanus, Antepipona luteipes, Antodynerus flavescens karachiensis, Celonites nursei, Cyrtolabulus karachiensis, Eustenancistrocerus (Parastenancistrocerus) baluchistanensis, Katamenes dimidiatus watsoni, Knemodynerus lahorensis, Leptochilus (Neoleptochilus) hina, Leptochilus (Neoleptochilus) mirificus, Leptochilus (Neoleptochilus) umerolatus and Tachyancistrocerus pakistanus...

The genus Polistes is revised for the West Palaearctic region based on morphology and DNA barcodes. The revision includes all known West Palaearctic species, raising the number of species in Europe to 14 and to 17 for the West Palaearctic realm. DNA barcodes were recovered from 15 species, 14 of which belong to the subgenus Polistes, and one, P. wattii , to the subgenus Gyrostoma. An integrative taxonomic approach combining morphology and molecular data (DNA barcoding) was employed to resolve longstanding taxonomic problems in this group...

The evolutionary success of hymenopteran insects has been associated with complex physiological and behavioral defense mechanisms against pathogens and parasites. Among these strategies are symbiotic associations between Hymenoptera and antibiotic-producing Actinobacteria, which provide protection to insect hosts. Herein, we examine associations between culturable Actinobacteria and 29 species of tropical hymenopteran insects that span five families, including Apidae (bees), Vespidae (wasps), and Formicidae (ants)...

The yellow-legged or Asian hornet (Vespa velutina colour form nigrithorax) was introduced into France from China over a decade ago. Vespa velutina has since spread rapidly across Europe, facilitated by suitable climatic conditions and the ability of a single nest to disperse many mated queens over a large area. Yellow-legged hornets are a major concern because of the potential impact they have on populations of many beneficial pollinators, most notably the western honey bee (Apis mellifera), which shows no effective defensive behaviours against this exotic predator...

Vespula germanica is a social wasp and an opportunistic predator. While foraging, these wasps learn and integrate different kinds of cues. They have successfully invaded many parts of the world, including native Nothofagus and Lophozonia forests located in the Andean-Patagonian region, where they forage on native arthropods. Perzelia arda, a lepidopteron defoliator of Lophozonia obliqua, uses the foliage to hide in and feed on. The purpose of this work is to study whether V. germanica use olfactory cues when foraging on P...
