A record of bilateral gynandromorphism in Epeolus (Hymenoptera: Apidae: Nomadinae) [PDF]
, 2018 The discovery of a gynandromorph of a North American Epeolus Latreille is reported. A specimen of E. flavofasciatus Smith from Flagstaff, Arizona, USA discovered in the collection of the American Museum of Natural History (AMNH) exhibits male-specific ...

Brood parasitism and egg recognition in three bunting hosts of the cuckoos
Ecology and Evolution, 2023 Comparative studies of egg recognition and rejection between various sympatric hosts provide insight into the coevolutionary history of the hosts and parasites, as well as the degree of antagonism between the species.

Heterospecific Hymenoptera found inside the nests of Bombus impatiens (Hymenoptera: Apidae). [PDF]
, 2018 The nests of social Hymenoptera are particularly attractive to species engaging in resource robbing due to their concentration of resources. Here, the identity of heterospecific intruders in Bombus impatiens nests are described, with a particular focus ...

Reducing cuckoo parasitism risk via informed habitat choices [PDF]
The Auk, 2017 ABSTRACT Brood parasitism incurs severe fitness costs for hosts. Diverse host adaptations to avoid parasitism exist at various stages of the host breeding cycle, but the literature suggests that egg-stage defenses are the most evolved. Fitness costs of parasitism would be minimized if hosts avoided parasitism prior to egg laying, but it remains unclear

Precisely targeting host activity for parasitism by Common Cuckoos
Avian ResearchThe evolution of parasitic strategies through tracking host life-history patterns represents a key adaptive trait in avian brood parasites. However, when hosts successfully exploit human-modified environments—such as diverse and concealed nesting sites ...

Born in an alien nest: how do social parasite male offspring escape from host aggression? [PDF]
PLoS ONE, 2012 Social parasites exploit the colony resources of social insects. Some of them exploit the host colony as a food resource or as a shelter whereas other species also exploit the brood care behavior of their social host. Some of these species have even lost

Extreme offspring ornamentation in American coots is favored by selection within families, not benefits to conspecific brood parasites [PDF]
, 2019 Offspring ornamentation typically occurs in taxa with parental care, suggesting that selection arising from social interactions between parents and offspring may underlie signal evolution.

Avian Research, 2019 Background Our knowledge of avian brood parasitism is primarily based on studies of a few selected species. Recently, researchers have targeted a wider range of host–parasite systems, which has allowed further evaluation of hypotheses derived from well ...
