Abstract
The tribe Anthidiini, from the family Megachilidae, includes cleptoparasitic and solitary species that nest in pre-existing cavities. In solitary species, females perform all nesting and oviposition activities without contact with their offspring. Although the life cycle of some solitary bees is known, the processes preceding the emergence of these individuals are still poorly understood. This study focused on the pre-emergent behavior of Ephanthidium tigrinum and Dicranthidium arenarium, using transparent trap nests for daily observation. Both active (movement; cell wall excavation; agonistic interaction; excavation of the closing plug and cleaning) and inactive (rest and sleep) behaviors were recorded. In both species, the emergence process began in the morning, days before the first bee emerged, suggesting a collective preparation. The study provides valuable insights into this behavior.
期刊介绍:
acta ethologica publishes empirical and theoretical research papers, short communications, commentaries, reviews and book reviews as well as methods papers in the field of ethology and related disciplines, with a strong concentration on the behavior biology of humans and other animals.
The journal places special emphasis on studies integrating proximate (mechanisms, development) and ultimate (function, evolution) levels in the analysis of behavior. Aspects of particular interest include: adaptive plasticity of behavior, inter-individual and geographic variations in behavior, mechanisms underlying behavior, evolutionary processes and functions of behavior, and many other topics.
acta ethologica is an official journal of ISPA, CRL and the Portuguese Ethological Society (SPE)
