ABSTRACT Euglossa Latreille, 1802 do not live in large colonies, and these are usually maintained or “reactivated” by new females, subordinate to their mother, which construct and provision brood cells. This study aimed to obtain information about the natural history of Euglossa cordata (Linnaeus, 1758) specially focusing on nest behavior. Our specific objective was to answer the following question: do E. cordata females reside in a single nest? We construct 14 artificial nesting boxes and made them available for E. cordata bees in natural environment for seven months. During this time, we use a re-marking method to identify bee fidelity to a single nest box. More specifically, we record bee permanence in the nests, the time bees take to provision brood to new cells and the time taken to offspring emergence. A total of 12 boxes were colonized by E. cordata and 23 cells were built in an average of 9.78 ± 11 days per cell. Eleven females emerged from the cells in 48.6 ± 11 days. Although adult females moved between nests and sometimes used multiple nests at the same time, E. cordata showed a relatively high fidelity to a single nest (81.1% of the female bees stayed in a single nest more than 50% of time).

Abstract. The orchid bees (Euglossini) are medium to large-sized species with fully or partially metallic body that are relatively common in the Neotropical Region. Nevertheless, the nesting biology of many species remains unknown. Therefore, the objective of this paper is to provide new information on the nesting biology of five species of Euglossini found in urban and forested sites of Brazilian Amazon. The nests of Eufriesea pulchra (Smith)and Euglossa chalybeata Friesewere recorded for the first time, found in an active nest of the ant Azteca sp. and in a fallen rotting tree, respectively. The nest of Euglossa townsendi(Linnaeus) was found in the leaf of an ornamental plant Cordyline sp. (Asparagaceae), also newly recorded. Euglossa intersecta Latreillewas recorded nesting in an abandoned termite nest, and Euglossa cordataCockerell was found nesting in a tubular metal window handle.Notas sobre a biologia de nidificação de cinco espécies de Euglossini (Hymenoptera: Apidae) na Amazônia BrasileiraResumo.

Abstract The genus Solanum (family Solanaceae) includes more than 1400 species and has buzz-pollinated flowers with poricidal anthers. The present study aimed to describe the distribution, breeding system and pollination mechanism of Solanum melissarum, a species endemic to Brazil. The study of breeding system was conducted in an urban forest fragment in Jataí, GO. Distribution data were gathered from floristic surveys and digital plant databases. The floral morphology and the pollination mechanism were studied on through field observations and preserved flowers. The breeding system was determined through hand pollination treatments. The species has a distribution only in the Brazilian Atlantic forest coastal, and this study provides the first records of S. melissarum for the state of Goiás. The pendulous flowers have poricidal anthers close to the stigma, with membranous thecae joined by a connective bearing osmophores that attract males of Euglossa cordata bees. As they collect fragrances, the bees press the thecae and pollen is released through a bellows mechanism. Based on the hand-pollination treatments, this species is self-incompatible. Isolated forest fragments may not include enough pollinators to ensure the pollination of plants with specialized systems. However, they are essential for the conservation of species with interesting phytogeographic patterns, such as the vicariance observed in S. melissarum, and for the conservation of regional diversity.

Components Analysis

Euglossini bees are considered pollinators of a wide variety of plants in the Neotropical region, but little is known about their floral preferences. In this study, we identified the botanical species used as pollen and nectar sources by three Euglossa species (Euglossa cordata, Euglossa townsendi, and Euglossa securigera) using pollen residue found in brood cells from trap nests installed in an urban fragment in São Luís, Maranhão, Brazil. In 14 analyzed Eg. cordata nests, 23 pollen types were observed, in 7 Eg. townsendi nests, 10 pollen types were observed, and in 1 nest of Eg. securigera, 6 morph types were identified. Solanum (Solanaceae), Zanthoxylum (Rutaceae), Mimosa pudica (Fabaceae), and Chamaecrista (Fabaceae) pollen types were common to all three bee species. Principal components analysis showed 83.04% variability on the first two axes, demonstrating substantial similarity among the samples. Solanum, Mimosa pudica, and Zanthoxylum were the principal components in the ranking. Larger diversity values (mean = 0.80) in some samples indicate that the species gathered resources in a heterogeneous manner; this resembles the findings of other studies of Euglossa. In general, the bees exhibited overlapping niches with regard to the most abundant pollens in the nests, but the females showed individual plasticity when gathering the floral resources.

The bee-plant community in a beach dune ecosystem in north-eastern of Brazil was studied concerning phenology and floral preference. The bees visited thirty-three species of 20 families of plants. The most visited species were Vernonia arenaria (Asteraceae), Chamaecrista hispidula (Caesalpiniaceae), Passiflora foetida (Passifloraceae) and Turnera melochioides (Turneraceae). Fifty-five percent of plants presented an annual or long flowering period (from 5 to 7 months). The largest number of species blooming was observed from March to August (dry season), corresponding to the period of greatest abundance and diversity of bees. Based on the range of floral sources used by the dominant bees, three guilds of bees were noted: bees with a restricted range of floral sources: Melitoma segmentaria, Centris tarsata, Centris flavifrons, Ceratinula sp.; moderate generalists: Megachile (Leptorachis) sp., Euglossa cordata, Augochlorella sp., Eulaema nigrita and Xylocopa frontalis; and generalists: Xylocopa cearensis, Apis mellifera, Exomalopsis analis and Pseudaugochloropsis pandora.
