Prey Items

Two females of Leptochilus regulus (de Saussure, 1855) were observed nesting in reed stalks of a Fabre’s hive serving as a block of trap nests in Crimea, with the timekeeping of all their nesting behaviours. The building material used by the females to separate the nesting cavity into the cells consisted of pellets of dry soil, gravel particles, and small fragments of tree bark, leaves, and thin stems. Females rapidly carried these items collected in 1.0–1.5 m from the nests. They bonded only the last portions of the building material in each “partition” with a very small amount of mud. An additional amount of unbonded building material items was deposited into the nest after sealing the last nest cell. Females hunted exclusively for small larvae of an anobiid beetle (Coleoptera, Anobiidae); they stored 19–37 prey items per cell. Hunting and provisioning occupied the largest portion of the females’ time budget. Duration of hunting flights was different between the females. The nests of both females contained three brood cells. Cocoons of Chrysis ragusae De Stefani, 1888 (Hymenoptera, Chrysididae) were found in the nests; females of this cuckoo wasp species were also recorded entering the host nests at the stage of provisioning, acting apparently as inquilines. The cocoon ultrastructure of L. regulus is illustrated and discussed.

Abstract Isodontia mexicana (Hymenoptera, Sphecidae), a New Invasive Wasp Species in the Fauna of Ukraine Reared from Trap-Nests in the Crimea. Fateryga, A. V., Protsenko, Yu. V., Zhidkov, V. Yu. - Th e North American wasp Isodontia mexicana was found for the first time in Ukraine in trap-nests operated near Pushkino (southern coast of the Crimea) in 2012. Th ree nests contained five cocoons, from which only one adult wasp emerged in 2013, allowing the positive identification; other cocoons were either empty (one) or destroyed by Melittobia acasta (three). Such a find of a newly established invasive species in Ukraine represents the easternmost point in its European range and possibly the most remarkable jump-dispersal event in its distribution.

Podium angustifrons Kohl 1902 is a species of solitary wasp which nests in pre-existing cavities, with neotropical distribution in Argentina, Bolivia, Brazil, Colombia, Guyana and French Guyana. The aim of this study was to investigate the nesting biology of P. angustifrons, discussing aspects of their life history. To capture its nests, wooden trap-nests were installed in the Parque Municipal das Araucárias, Guarapuava (PR), Brazil, from January 2003 to April 2009. A total of 29 nests were collected, all during the warmer months. These showed no vestibular and intercalary cells, and their closures were made up of chewed plants and mud mixed with organic materials and resin-coated surfaces, sometimes showing a layer of lichens. The cells were provisioned with various wild species of cockroaches (Chorisoneura sp, Riata sp and Helgaia sp) in the nymph stage and/or adults. The sex ratio was 4.6 females per male, significantly higher that the expected 1:1. Most pre-pupae entered diapause in winter with development time ranging from 187 to 283 days for females and 180 to 283 days for males. Deaths occurred in 41.66% of cells provisioned, 33.33% were attributed to faulty development and 8.33% to Chrysididae.

Trap Nest

The nesting biology of Hoplitis producta has been reported by several authors, as the species is a common and widely distributed bee in North America east of the Rocky Mountains. Additional records, which have been obtained in connection with trap-nest research on bees and wasps in Wisconsin, are provided to supplement the previous reports.The nests were found in the pith at the butt ends of sumac stick trap-nests. A nest could be recognized readily because the 3 mm. plug that closed the burrow had a more solid texture and a darker color than the surrounding pith at the end of the stick. Rau (1928) found nests in tunnels of elder, sumac or rose stems but could not ascertain whether the bee excavated its own burrows or utilized burrows left by other twig-dwellers. Fischer (1955) stated that the female almost invariably excavated its own burrow. In Wisconsin, freshly cut sumac sticks were placed in the field in the spring; therefore, each of the following records represents a nest in a burrow excavated by the foundress bee.

(1) Background: Landscape simplification is a major threat to bee and wasp conservation in the tropics, but reliable, long-term population data are lacking. We investigated how community composition, diversity, and abundance of tropical solitary bees and wasps change with landscape simplification (plant diversity, plant richness, distance from forest, forest cover, and land use type) and season. (2) Methods: We installed 336 timber and cob trap nests in four complex forests and three simplified orchards within the subtropical biodiversity hotspot of south-east Queensland, Australia. Trap nests were replaced every season for 23 months and all emergents identified. (3) Results: We identified 28 wasp species and 13 bee species from 2251 brood cells. Bee and wasp community composition changed with landscape simplification such that large, ground-nesting, and spider-hunting species were present in all landscapes, while those with specialist resource requirements and (clepto) parasitoids were present only in complex landscapes. Abundance and diversity of bees and wasps were unaffected by landscape simplification but increased with rainfall. (4) Conclusions: This study highlights the need for multi-year studies incorporating nuanced measures such as composition with a focus on functional diversity to detect changes bee and wasp populations.

First Time

Nesting of Leptochilus limbiferus (Morawitz, 1867) was observed in the Krasnodar Territory, Russia. Twelve nests were studied; all of them were located in empty shells of a terrestrial snail species, Xeropicta derbentina (Krynicki). The building material used by the wasps was pellets of dry soil and gravel particles, as well as shell bits, and sometimes also tiny shells. Females hunted for caterpillars of a gelechiid moth Syncopacma coronillella (Treitschke) and two unidentified species. Imagoes of L. limbiferus were observed feeding on nectar at flowers of five plant species in five families. Males were also observed patrolling the nesting site and sleeping inside a shell of X. derbentina. Nests were invaded by ants and an anthracine fly. Nesting activity and structure of the nests and cocoons are described in detail. The species is univoltine; hibernation occurs at the prepupa stage. The present contribution is the first detailed report on the bionomics of the subgenus Euleptochilus Blüthgen, 1943. Nesting of Old World species of Leptochilus de Saussure, 1853 is discussed with special reference to use of gravel as building material in two phylogenetic lineages: Leptochilus and unrelated genus Alastor Lepeletier de Saint-Fargeau, 1841. The distribution of L. limbiferus is summarized; particularly, the species is reported from Montenegro and Azerbaijan for the first time. At the same time, its previous records from Armenia were found to be based on a misidentification of Leptochilus (Euleptochilus) duplicatus (Klug, 1835) (new for Armenia and the Caucasus as a whole). Leptochilus limbiferus anatolicus Blüthgen, 1955 and L. limbiferus achaeus Gusenleitner, 1970 are treated as synonyms of L. limbiferus s. str. (new synonymies). The lectotype of Odynerus limbiferus Morawitz, 1867 is designated. A key to subgenera of Leptochilus is provided.

Nesting of Stenancistrocerus obstrictus was studied in the Republic of Dagestan, Russia. Ten nests were observed, six of them were dissected and their structure was studied. The nests were located in preexisting holes in a clayey cliff. Females searched for a place for the nest during more than a day. The holes with nests were 2.5–10.5 cm in length and 3–4 mm in diameter. Nest entrances were surmounted by laced earthen turrets curved downwards. The maximum length of a turret was 2 cm; the turrets had more laced structure at their distal ends while they became more solid towards the base. Nests consisted of a row of 3–10 cells separated by thin mud partitions. The cells were 5–9 mm in length. All lateral walls of the cells, as well as the vestibular cell were lined with a thin layer of mud. Females collected the building material outside the nests; they mixed clayey earth with regurgitated liquid and formed mud pellets used for the nest construction. Complete nests were sealed by final plugs; their turrets were dismantled by the females. The provision was tiny larvae of an unidentified curculionid beetle; several dozens of them were stored per cell. No parasites and associates were found in the nests. Reproductive success amounted to 92%. Adult feeding was recorded on flowers of Tamarix hohenackeri. The species is univoltine; hibernation occurs at the prepupa stage. Adult wasps are active from the end of May to the end of July. Nesting biology of the genus Stenancistrocerus and its phylogenetic position are discussed. Such a type of the nesting could be regarded as intermediate between nesting in various preexisting cavities and the excavation of burrows in an earthen substrate. The distribution of S. obstrictus is summarized; it includes Russia (Astrakhan Prov., Kalmykia, Stavropol Terr., Dagestan), Armenia, and Azerbaijan; the presence of the species in Eastern Europe is confirmed. The lectotype of Odynerus obstrictus Morawitz, 1895 is designated.

This study was carried in the Parque Municipal das Araucárias in the municipality of Guarapuava, state of Paraná, Southern Brazil. Three hundred and sixty five nests of T. lactitarse were obtained using trap-nests of 0.7, 1.0, and 1.3 cm in diameter. All of them had similar architecture, regardless of the diameter of the trap-nest. Completed nests consisted of a linear series of brood cells whose average number per nest was of 3.3, 4.0 and 3.6 for the nests with 0.7 cm, 1.0 cm and 1.3 cm in diameter, respectively. They were constructed more often during the summer. T. lactitarse had two types of life cycles: direct development (without diapause), and delayed development (with diapause during winter). Natural enemies included Chrysididae, Sarcophagidae, Dolichopodidae and Ichneumonidae. Out of 1,353 identified spider prey, 1,313 belonged to the Araneidae family.

Do So

By using trap nests, a total of 1,752 nests containing 3,405 provisioned cells of 33 species of solitary wasps and bees belonging to Vespidae, Sphecidae, Crabronidae, Pompilidae and Megachilidae families were collected in North Vietnam. Although the trap-nests are placed throughout the year, the nests were only collected in the period of seven months per year, from mid-April (or early May) to early November. A larger number of the nests (n = 1,607, or 91.72%) were occupied by wasp species and only 145 nests (8.28%) were occupied by bee species. In each family, Vespidae, Megachilidae, Sphecidae, Crabronidae and Pompilidae were represented by 12, 11, 7, 2 and 1 species, respectively. The dominant species were Pareumenes quadrispinosus, Rhynchium bruneum (Vespidae) and Chalybion malignum (Sphecidae). The nesting activities of wasps in the summer (May to July) were more active than in the autumn (August to early November), while the highest number of nests of bees were recorded in June, October and November. Tổng số 1.752 tổ chứa 3.405 khoang tổ của 33 loài ong bắt mồi thuộc các họ Vespidae, Sphecidae, Crabronidae, Pompilidae và ong mật họ Megachilidae đã được thu thập trong bẫy tổ ở miềm Bắc Việt Nam. Mặc dù các bẫy tổ được đặt trong cả năm nhưng tổ của các loài ong bắt mồi và ong mật chỉ thu được trong khoảng thời gian từ giữa tháng 4 (đầu tháng 5) đến đầu tháng 11. Phần lớn các tổ được làm bởi các loài ong bắt mồi (1.607 tổ chiếm 91,72%), chỉ có 145 tố chiếm 8,28% được làm bởi các loài ong mật. Số loài làm tổ thuộc các họ Vespidae, Megachilidae, Sphecidae, Crabronidae và Pompilidae tương ứnglần lượt là 12, 11, 7, 2 và 1. Trong đó có ba loài phổ biến là. Pareumenes quadrispinosus, Rhynchium bruneum (Vespidae) và Chalybion malignum (Sphecidae). Hoạt động làm tổ của các loài ong bắt mồi từ tháng 5 đến 7 diễn ra tích cực hơn so với từ tháng 8 đến 11, trong khi đó số tổ của các loài ong mật lại thu được nhiều nhất trong ba tháng 6, 10 và 11.
