We described the nesting behavior and ecology of Diadasina riparia, from an urban dry forest fragment. The nests of D. riparia were shallow with circular entrance, closed by a mud plug, from which a straight vertical tunnel ending in one or more brood cells. Most females need one day for construction and provisioning the nest. The natural enemies were flies of Anthrax genus, the cleptoparasitic bees Leiopodus trochantericus, and Mutillidae wasp. The feature about the life history, nest architecture, materials used, pollen provisions behavior and associated organisms of this species allow the comparison with other emphorines species.

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.

Obtaining knowledge about a species’ life history and reproductive behaviour is fundamental for understanding its biology, ecology, and potential role in ecosystem services. Here, we focused on the dung beetle species Onthophagus lecontei. Adults were collected in the field and then confined to terrariums, where they were supplied with semi-fresh domestic goat dung (Capra aegagrus Erxleben, 1777). After being paired (26 pairs), the nesting behavior of beetles was observed under laboratory conditions and the preimaginal development of individuals obtained from mating (from the deposition of the egg until the emergence of the adult) was described. Their nesting behavior was found to be characteristic of what is known as pattern I, which comprises building of brood masses, oviposition of a single egg in each brood mass, development of three larval instars, construction of a pupation chamber, pupal stage and adult emergence. Both sexes were involved in the handling of dung, tunnel construction, and mass nest elaboration. Pairs built from one to seven brood masses. The pre-nesting period (feeding) lasted 16 days; the egg stage two days, the larval period 22 days; the pupal period 11 days and the imagoes four days, after which the adults emerged. Our results are discussed and compared with other species in the genus. However, our knowledge of this dung beetle is still limited, and further studies are required in all areas of its biology.

We provide information on the nesting behavior, seasonality and nest soli type characteristics of Eucera nigrilabris Lepeletier, 1841 in Egypt. A nest was discovered in a canal bank in Abbis Village, Alexandria, Western Egypt. The species is protandrous, univoltine, ground nesting species. The bees built deep nests about 85cm under the ground and consisted of lined, branched tunnel with many cell. The bees start fly by end of January until end of March and active in winter seasons. The soil of the nest has yellow color, sandy loam texture, low salinty and sodicity, and low calcium carbonate content. The bee distrbiution was influnced by the soil with high content of sodium carbonate. The bees forage on the wild flora of the family Asteraceae carriyng a yellow pollen load. There is no any record of a cleptoparasitism around the nesting area.

We report here on a new species of Neocorynura from southern Costa Rica, only the third in this large (~150 spp.), primarily ground-nesting genus known to nest in wood. We describe the male, female, pupa, and nest of Neocorynura tica Smith-Pardo sp. nov. and provide information on its nest architecture and natural enemies. Neocorynura tica are small (~7 mm long), dark green bees with metallic greenish-yellow highlights and can be distinguished from most other Neocorynura by their small size and lack of metatibial spine, and especially from the allopatric N. rhytis (Vachal) by the lack of sculpturing on the mesoscutum and mesoscutellum. We found the cleptoparasitic phorid fly Megaselia sp. and a larva of a putative mutillid wasp attacking brood provisions of N. tica. Adults of N. tica were caught only in fragments of moist tropical forest, despite intensive sampling in nearby agricultural countryside, suggesting that this species may be forest-limited. We review existing information on nesting, social behavior, and parasitism in the genus, and briefly discuss the evolution of wood nesting behavior in the genus Neocorynura.

Abstract Variation in annual rainfall is considered the most important factor influencing population dynamics in dry environments. However, different factors may control population dynamics in different microhabitats. This study recognizes that microhabitat variation may attenuate the influence of climatic seasonality on the population dynamics of herbaceous species in dry forest (Caatinga) areas of Brazil. We evaluated the influence of three microhabitats (flat, rocky and riparian) on the population dynamics of four herbaceous species (Delilia biflora, Commelina obliqua, Phaseolus peduncularis and Euphorbia heterophylla) in a Caatinga (dry forest) fragment at the Experimental Station of the Agronomic Research Institute of Pernambuco in Brazil, over a period of three years. D. biflora, C. obliqua and P. peduncularis were found in all microhabitats, but they were present at low densities in the riparian microhabitat. There was no record of E. heterophylla in the riparian microhabitat. Population size, mortality rates and natality rates varied over time in each microhabitat. This study indicates that different establishment conditions influenced the population size and occurrence of the four species, and it confirms that microhabitat can attenuate the effect of drought stress on mortality during the dry season, but the strength of this attenuator role may vary with time and species.

We present a commented taxonomic list of the reptiles found during herpetological surveys carried out in an isolated fragment of tropical dry forest located in the municipality of San Francisco, Zulia state, northwestern Venezuela between January-December 2011. We report a total of 24 species belonging to the order Squamata, distributed in 12 families and 21 genera. Colubridae is the most diverse family with six species, followed by Dipsadidae (four species), Boidae, Gymnophthalmidae, Phyllodactylidae and Teiidae with two species each, and finally Dactyloidae, Iguanidae, Elapidae, Gekkonidae, Sphaerodactylidae and Viperidae with a single species each. The species composition at this site matches what would be expected in a tropical dry forest in the region. Our study suggests that this isolated tropical dry forest fragment is the last refuge of the herpetofauna that once occupied much of the dry forests of the northern Maracaibo basin and should therefore be considered for conservation purposes.

Urban areas, as cities, are frequently overlooked as refuges for the native fauna. However, these places may support several species and house relevant biodiversity contributing to important ecosystemic functions. Wasps and bees (Hymenoptera: Apocrita) are important faunistic elements acting as predators/parasitoids and pollinators, respectively. Therefore, they must be surveyed and inventoried for conservation purposes, especially in cities located in the Atlantic Forest domain, a ravaged Brazilian biome. Accordingly, this study presents a species list of trap-nesting bees and wasps that occurs at the Jardim Botânico do Rio de Janeiro. The survey was conducted using the trap-nest method. Three types of trap-nests were offered totalizing 1,038 traps: rubber hose, bamboo cane and plastic straw. The plastic straw traps were the most effective followed by the bamboo cane ones at attracting nesting wasps and bees. Between April/2017 and February/2019, 12 foundress species built nests: Tetrapedia curvitarsis (Apidae) (33 nests), Hylaeus sp. (Colletidae) (6), Auplopus cf. rufipes (Pompilidae) (5), Trypoxylon sp. (Crabronidae) (4), Pachodynerus nasidens (Vespidae) (3), Auplopus cf. brasiliensis (Pompilidae), Megachile benigna and Megachile sp. (Megachilidae), Euglossa pleosticta, Euglossa sp., and Eufriesea sp. (Apidae) and Penepodium sp. (Sphecidae) all with one nest. Also, four natural enemies were recorded: Chaenotetrastichus neotropicalis (Eulophidae), Gasteruption brachychaetum (Gasterupteiidae), Caenochrysis crotonis (Chrysididae) and Amobia sp. (Diptera: Sarcophagidae). Most bee nests were restrained to the matrix forest and nearby areas, whereas wasps built their nests predominantly in open areas. Regarding seasonality, bees tended to nest in the summer and early autumn influenced by mean temperature, in contrast of wasps that nested in late autumn, winter and spring, influenced by pluviosity. Besides many rare species, which suggests environmental disturbance, the Jardim Botânico do Rio de Janeiro showed a fairly diverse fauna and shows how forest fragment in cities may harbour important representatives of the native fauna.
