Bombus Pullatus
''Bombus pullatus'' is a tropical, eusocial species of bumblebee native to Mexico and Central America. Unlike many bumblebee species, they live in colonies with multiple queens. Distribution & Taxonomy The majority of this species occurs in the lowlands of Central America, with approximately 90% of colonies being found in Costa Rica. However they have been found at elevations higher than 3 km above sea level. Colonies have been confirmed in Guatemala, Honduras, Nicaragua, Panama and the south of Mexico. ''Bombus pullatus'' is considered a more basal member of the genus ''Bombus'' compared to ''Bombus pauloensis'' and ''Bombus transversalis''. Historically, ''Bombus pullatus'' has commonly been misidentified as ''Bombus pauloensis'' and vice versa in many collections. Molecular analyses (such as DNA profiling) of these specimens are required to accurately identify both species. This issue is why the IUCN has agreed to reject data on this species that is more southern than Panama. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eusocial
Eusociality (from Greek εὖ ''eu'' "good" and social), the highest level of organization of sociality, is defined by the following characteristics: cooperative brood care (including care of offspring from other individuals), overlapping generations within a colony of adults, and a division of labor into reproductive and non-reproductive groups. The division of labor creates specialized behavioral groups within an animal society which are sometimes referred to as 'castes'. Eusociality is distinguished from all other social systems because individuals of at least one caste usually lose the ability to perform at least one behavior characteristic of individuals in another caste. Eusocial colonies can be viewed as superorganisms. Eusociality exists in certain insects, crustaceans, and mammals. It is mostly observed and studied in the Hymenoptera (ants, bees, and wasps) and in Blattodea (termites). A colony has caste differences: queens and reproductive males take the roles of the so ...
