“…Their phylogeny had indicated Ericrocidini and Rhathymini as sister groups, and Ericrocis as sister to all Ericrocidini. Ericrocidini primarily parasitize nests of Centris (although Mesoplia rufipes can also attack nests of Epicharis ; see Rocha‐Filho et al ., and references therein) and Rhathymini parasitize only species of Epicharis (Michener, ; Werneck et al ., ).…”

Cleptoparasitic bees abandoned pollen‐collecting for their offspring and lay their eggs in other bees' provisioned nests. Also known as cuckoo bees, they belong to several lineages, but are especially diverse in Apinae. We focused on a lineage of apine cleptoparasitic bees, the clade Ericrocidini + Rhathymini, which attack nests of oil‐collecting bees. We sequenced five genes for 20 species in all genera of this clade plus a large outgroup to reconstruct the phylogeny and estimate divergence times. We confirmed the monophyly of the clade Ericrocidini + Rhathymini and its position inside the ericrocidine line together with the tribes Protepeolini, Isepeolini, Osirini and Coelioxoidini. Our results corroborated the current taxonomic classification. Ericrocis is sister to all Ericrocidini and the position of Acanthopus and the most diverse genus Mesoplia were inconclusive. Ericrocidini + Rhathymini diverged from other apine cleptoparasitic lineages 74 Ma in the Cretaceous and from each other in the Palaeocene at 61 Ma. Considering the robust molecular evidence of their sister relationships, the striking differences in the morphology of first‐instar larvae of the two groups may represent adaptations to the nesting biology of their hosts. As other cleptoparasites in the ericrocidine line, Ericrocidini and Rhathymini possess larvae which are adapted to kill the immature host and to feed on floral oil provided by the host female. The evolution of host specialization in the line Ericrocidini + Rhathymini retroceded to the Eocene when they differentiated synchronously with their hosts, Centris and Epicharis.

“…In the remaining four cells, there were mature larvae of R. friesei. Larvae of R. friesei were easy to identify due to the presence of their cocoon (see Rozen 1969;Camargo et al 1975;Werneck et al 2012).…”

“…The natural enemies of Epicharis, include parasitoids, cleptoparasitic, and predatory insects. Bees of the genus Rhathymus (Apidae, Rhathymini) are known to be specialized cleptoparasites of Epicharis' nests (compiled by Werneck et al 2012), although there are also more generalized cleptoparasites, such as those of the genus Mesoplia Lepeletier, 1841 (Apidae, Ericrocidini) which also attack nests of Centris (Gaglianone 2005;Rocha-Filho et al 2008;Rocha-Filho et al 2009;Vivallo 2020a). Besides bees, there are records of Epicharis as a host for both cleptoparasitic species of Meloidae (Coleoptera) and parasitoid species of Conopidae (Diptera) and Mutillidae (Hymenoptera) (Gaglianone 2005;Rocha-Filho et al 2008;Gaglianone et al 2015).…”

This study investigates the nesting habits of Epicharis picta in a nest aggregation located in a fragment of the Atlantic forest in Southeastern Brazil. Ten emergence-traps were set up in this nest aggregation to standardize data collection of phenology, natural enemies, and sex ratio. Epicharis picta nests were in an area of 160 m² with a density of 41 nests/m². Nest and cell architecture are described. Epicharis picta is a protandrous, univoltine species with its emergence in this study occurring between 28 January and 15 April. We provide direct evidence of parasitism on E. picta by Rhathymus friesei, Tetraonyx sexguttata and T. aff. lycoides. The predator Apiomerus lanipes was found to prey Epicharis for the first time. We suggest the use of emergence-traps as tools to support studies of ground-nesting bees. In addition, we compile, update, and discuss data on the nesting biology of all Epicharis subgenera.

“…For many of the cleptoparasites, the exact host is not known (Sheffield et al 2013b). Thus a genus or genera that many species in the cleptoparasitic genus take advantage of is used as a potential host genus (Werneck et al 2012). This makes it difficult to say if the specific host is present along with the parasite.…”

First, I would like to thank my family and friends for their continued support and encouragement throughout my time at Iowa State University. You all have been immensely helpful and supportive from day one of my research and I greatly appreciate all that you have done for me. Thank you to M. Mackert, S. Klein, J. Latimore, K. Vance, and S. Jones for all of your assistance with field work; a job I could not have done alone. A special thank you to my fellow graduate students, and E. Altrichter, C. Anderson, R. Arndorfer, R. Reeves, and B. Towery for all of your support and help with preparation for field work. And thank you to K. Rey for your help with all of the statistical support and guidance you have given me. I would particularly like to thank my co-major professor, Mary Harris for all of her guidance and support throughout the course of this research. I would additionally like to thank my other co-major professor, and Brian Wilsey, and my committee member, Bob Klaver, for their help along the way. Thank you to the Farm Service Agency for funding this project. Also thank you to Iowa State University for providing me with a teaching assistantship. And lastly, thank you to all of my landowners for providing me access to their land to complete this research.
