Cavity-nesting Hymenoptera in Disturbed Habitats of Georgia and South Carolina: Nest Architecture and Seasonal Occurrence

Nesting biology of two species of Megachile (Moureapis) (Hymenoptera: Megachilidae) in a semideciduous forest reserve in southeastern Brazil

“…Although Megachile nesting ecology has been reasonably well studied in Europe and North America (e.g., Michener 1953;Hobbs and Lilly 1954;Krombein 1967;Richards 1978;Eickwort et al 1981;Raw 1984Raw , 1988Williams et al 1986;Cane et al 1996;Barthell et al 1998;Kemp and Bosch 2000;Armbrust 2004;Jenkins and Matthews 2004;Pitts-Singer and Cane 2011), it has been poorly investigated in Brazil with few works published, frequently with only incomplete information (von Ihering 1904;Laroca 1971Laroca , 1987Blochtein and Wittmann 1988;Martins and Almeida 1994;Almeida et al 1997;Zillikens and Steiner 2004). For the subgenus Moureapis, only fragmentary information is available on nests of a single species (Megachile apicipennis Schrottky, 1902) (von Ihering 1904;Laroca 1991).…”

The Phenology and Spatial Distribution of Cavity-Nesting Hymenoptera and Their Parasitoids in a California Oak-Chaparral Landscape Mosaic

“…This diverse group of hymenopterans includes several ecological guilds (pollinators, predators, and parasitoids) and often comprises insect communities with high species richness and trophic diversity (Ebeling et al, 2012). Although these species are widespread within the natural world, much of our knowledge of their ecology comes from studies performed in agricultural and other human-managed landscapes (e.g., Steffan-Dewenter and Leschke, 2003;Jenkins and Matthews, 2004;Loyola and Martins, 2006;Holzschuh et al, 2009). In comparison, few have investigated the biotic and abiotic conditions that drive changes in abundance and spatial distribution within natural landscape mosaics (but see Sobek et al, 2009).…”

“…Augmenting aboveground nest habitat (''trapnesting'') is a widely used survey method that can provide a wealth of information on cavity-nesting species, including species diversity, abundance, phenology, associated habitat, prey usage, parasitism, and nest architecture (Jenkins and Matthews, 2004). In this study we used this survey technique over 3 y in order to answer the following questions: (1) What is the seasonal phenology of a cavity-nesting hymenopteran community in its native habitat?…”
